Various changes from Deadman: Annihilation meant to make the gamemode more accessible have been reverted. This changes include the return of bank keys, the removal of lootable Deadman’s chests, and the removal of Ancient Warriors’ armour, among other changes.^[1]

For quests, Temple of Ikov, The Dig Site, The Tourist Trap, Troll Stronghold, Waterfall Quest, Regicide, One Small Favour, Beneath Cursed Sands, and Monkey Madness II are auto-completed.

For gear changes, godswords drop in their fully completed state from God Wars Dungeon, and all uniques from Nex are dropped in their repaired/completed state. Additionally, if a piece of Ahrim the Blighted’s equipment is rolled on the Barrows drop table, players will instead receive the equivalent Karil the Tainted’s equipment piece. Finally, the boot slot is now available, as a RuneLite plugin is used to visually indicate the members of each team, rather than requiring competitors to wear coloured boots.

All safezones except for Varrock have been removed. Players will spawn, respawn, and can home teleport to the Grand Exchange. Safe deposit boxes have been removed and replaced with a designated team storage NPC which can hold up to 40 tradeable items accessible by any member of their team.

Sigils are not obtainable as a drop or purchaseable from the skull shop (which has been fully removed). Instead, all players start with eight sigils in their bank: consistency, finality, aggression, rampage, arcane swiftness, gunslinger, swashbuckler, and lightbearer. No other sigils can be obtained in any way.

Breaches will return, functioning similarly to those in season 2. They will spawn once a day at 20:00 BST in a multi-combat area and last for 30 minutes. Breach monsters will drop Ancient Warriors’ weapons at a rate in 1/90 and corrupted weapons at a rate of 1/80, and attacking a breach monster skulls the player. The breaches will take place in the following locations:

• Day 1: Mole Hole
• Day 2: Rogues’ Castle
• Day 3: Al Kharid (multicombat area expanded to the south and east to include the Shantay Pass and Kalphite Cave entrance)
• Day 4: Middle of the Wilderness
• Day 5: South Varlamore (near the Colossal Wyrm Remains)
• Day 6: Mor Ul Rek
• Day 7: Ape Atoll
• Day 8: Port Piscarilius (multicombat area expanded to the north-east to include the bank and anglerfish fishing area)

Twice a day, a mission will be posted for all teams, at 16:00 BST and 00:00 BST. Missions vary in difficulty but always requiring a specific boss or monster to be killed. The monster will drop a mission totem, which must be brought back to the totem trader at the Grand Exchange to complete the mission and claim the reward. The player currently holding the totem will be marked with a red skull, and if killed in PvP, the totem will be lost to the player who killed them, who can turn the totem in for their team instead.

Rewards for turning in a mission totem vary from tier 4 (gear useful for progression) to tier 1 (best-in-slot gear for the finale), with later missions rewarding better gear.^[2]

While teams do not know the exact mission or reward in advance, they do know the tier that each mission rewards:

• Day 1: Tier 2, Tier 4
• Day 2: Tier 4, Tier 3
• Day 3: Tier 3, Tier 3
• Day 4: Tier 3, Tier 2
• Day 5: Tier 3, Tier 1
• Day 6: Tier 2, Tier 2
• Day 7: Tier 3, Tier 1
• Day 8: Tier 2, Tier 1

Killing other players during the week rewards the killer’s team with blood money. Kills in single-way combat or later in the week will reward more blood money than those in multicombat areas, at breaches, or later in the week. Dying removes 1 blood money from a team’s total, regardless of time or location. A team can never have a negative amount of blood money.

Blood money can be spent on upgrades for use exclusively in the finale. Available upgrades are arcane and dexterous prayer scrolls, trinkets of vengeance with two charges, and Saradomin brew upgrades (replacing one anglerfish in the finale inventory). The price of each upgrade increases each time it is purchased. Additionally, the Vesta’s longsword, Zuriel’s staff, Morrigan’s javelins, and Morrigan’s throwing axes are available for purchase but can only be purchased once per team.

Sigils will be banned during the finale. Other banned items, spellbooks, actions, etc. include:

• Entity Hider, ::renderself, or the Death Dotter plug-in.
• The Lunar or Arceuus spellbooks
• Phoenix necklaces
• Prayer regeneration potions
• Extra Hitpoints gain through non-PvP means
  • HP gain from special attacks and blood spells is allowed
• Rock cakes, locator orbs, or any other item that lowers a player’s Hitpoints intentionally
• >1 ring of recoil
  • Rings of suffering can have any number of charges
• Pre-potting before a player enters for their team’s match
  • Players can pre-pot “in line” while waiting for their turn once their team’s match has begun
• A player placing bets on themselves or other teams
• Pre-seeding the arena with mithril or adamant seeds

All players will begin with a base inventory consisting of a ranging potion, supercombat potion, two Saradomin brews, three Sanfew serums, and nine anglerfish. Anglerfish can be upgraded to Saradomin brews by spending blood money earned by killing other players throughout the week.

Gemstone crab locations in Tlati rainforest

Children of the Sun must first be completed to access Varlamore. The Civitas illa Fortis Teleport or quetzal whistle can be used to reach the quetzal transport system, which can be used to fly to Tal Teklan to reach the Tlati Rainforest for the first time. From there, run south to the crab nest. Each gemstone crab nest has a cave that leads to the location of the fight, or the next respawn location if between fights. If there is no crab at the location you arrive at, simply use the cave to reach the correct area. After each fight, this is also used to reach the next crab respawn point.

Other methods to reach the gemstone crab include:

• A charged Pendant of ates can be used to teleport just north of Kastori after activating the Statue of Ates located there. From here, the player can run north to reach the eastern gemstone crab site.
• The Quetzal landing site that must be built at Kastori, which is about the same distance to the eastern crab nest as the Tel Teklan quetzal is to the southern crab nest.
  • The Hunter cape teleport to the Hunter’s guild is also next to a Quetzal landing site
• Fairy ring code AIS to Auburn Valley. From here, the player can run south west to Achilka, who can take them to both Tal Teklan or Kastori, with both boat endpoints being close to gem crab nests to their north.
• If lacking any of the methods above, walking from Civitas illa Fortis to the Quetzacalli Gorge is safe and there is a mountain guide who will take you to Nemus Retreat. From there you can walk south to Achilka and take her boat.

Strategy

Unlike most monsters, the crab does not die. It has effectively infinite health and remains in its nest for 10 minutes before burrowing. As a result, fighting it serves as an idle training method, allowing players to gain combat experience with minimal interaction and little to no downtime.

Almost any equipment can be used effectively, and players of all levels can participate. The crab has no defensive stats, but and can only hit for 1 damage to players it is facing. Strength bonus should be prioritised to maximise experience gain.

Players may wish to consider using low level prayers like Burst of Strength which will always increase max hit, while draining prayer extremely slowly.

Although reduced by 12.5%, experience rates at the crab are still generally favourable, especially for mid level and higher level players. Melee is the most effective combat style when training against the gemstone crab. Ranged training may be worthwhile at the crab at lower levels, especially before unlocking better methods such as chinchompas. Magic isn’t recommended, as it is inefficient at all levels. A low level player is recommended to read the section on magic further down the page for more information.

The gemstone crab does not count as a crab for the sake of slayer tasks, and so the slayer helmet (i) provides no benefit here.

Equipment

When selecting gear, the primary consideration is maximizing damage to increase experience gain. The crab’s minimal defensive stats and high health make nearly all weapons viable for consideration; players should be able to use whatever their best weapon is already.

At very low combat levels, weapons like the goblin paint cannon can still perform well due to their fast attack speed.

For higher levels, blood moon armour set with the dual macuhuitl is often best-in-slot.

Melee

For lower levelled players, some of the other armour sets may be too expensive, or not yet able to be equipped due to current levels or quest progression. The main stat to prioritise is still Strength bonus, although at a lower level not as many items exist for increasing it. Wearing Prayer bonus gear like Monk’s robes is best if you are unable to get anything else for that slot, if planning to use offensive prayers like Burst of Strength or Ultimate Strength. Prioritise your budget towards the most effective weapon first, as it will have the largest effect on your damage. Most weapons will work, although it is recommended to use faster weapons like scimitars or swords.

The blood moon armour set with the dual macuahuitl provides some of the highest damage-per-second and the best experience rates for melee. Using any other weapon, head, torso, or leg slot item will not allow usage of the set effect that increases your attack speed however, so they cannot be changed for gear with better or worse stats without losing a large portion of your DPS.
It will cost the most to upkeep however, at 100,000 gp/hr if repairing the armour with an NPC such as Bob.

2.  Will damage the player, but not below 4 HP, so it is safe to use.
3.  To save on using Super strength potions.
4.  To reduce prayer potion usage.

The obsidian set is a solid choice that can match up to max gear. The strategy centres around combining obsidian armour, the berserker necklace and the Toktz-xil-ak. These items synergise to grant the player a set bonus, which increases damage output by 30%. The base damage for this set is relatively low, due to its low strength bonus. It therefore relies on other boosts to increase damage output; its 30% damage increase allows other strength boosts to scale much better. With other boosts, such as Ultimate Strength/Piety and super strength potions, the damage output can rival that of much more expensive gear sets. The accuracy penalty is negligible when fighting the gemstone crab, as it has no defensive stats.
This setup does not consume charges, unlike with Blood moon armour and Dharok’s equipment. This can save a considerable amount of gp, as blood moon costs 100,000 per hour to use, and dharok’s costs 22,000 per hour, assuming that one repairs using an NPC such as Bob.

1.  With void armour. See the “lower level” tab for weapons to use with this set.
2.  If using offensive Prayers, and if it doesn’t lose a max hit
3.  May be worse than using another set, check DPS rates before using
4.  To save on using Super strength potions.
5.  To reduce prayer potion usage.

Dharok’s equipment can provide the best damage output, but requires the player to remain at very low Hitpoints. It is recommended to have at least level 90 or more Hitpoints to gain the full effect of the armour set, as with less than this blood moon or obsidian armour sets are likely to be more damage, although it is best to calculate with your own gear and levels. To maximise the effect of the armour, the player should remain between 2-4 Hitpoints for the whole encounter, although players with 99 Hitpoints can still maintain higher damage than other sets while only resetting their Hitpoints between each crab fight. You can prevent Hitpoints from regenerating by turning on and off the Rapid Heal prayer at least once per minute, and damage yourself down with the use of any item that can deal damage to yourself, namely the locator orb or dwarven rock cake.
While not often, the gemstone crab can deal lethal damage, so do not drain your Hitpoints all the way to 1. It is good to take some food that heals a small amount multiple times, such as cooked crab meat, guthix rest, or sacks of vegetables, in order to restore Hitpoints in case of accidentally draining them to 1, or getting hit down from 2. Just like the obsidian armour set, due to the Dharok’s set boosting damage by a percentage, Strength bonus gear in the remaining slots is especially potent for boosting damage output.

Melee inventory

Fighting the gemstone crab does not require any items, although some may be brought to increase damage dealt at the cost of reducing AFK time:

• Super strength potions, or Strength potions. Black warlock mixes can also be used, and will share the Strength buff to other nearby players, but have low trade volume. Several black warlocks spawn to the east of the southern and northern crab nests, and south of the eastern nest; with 55 Hunter they can be caught before initiating combat with the crab to boost Strength.
• Bring a method to reach the crab, such as a Pendant of ates, quetzal whistle, or runes for Civitas illa Fortis Teleport. Banking can be done in Tal Teklan, so holding onto it isnt necessary.
• (Optional) Prayer restoring items such as prayer potions if using offensive prayers to increase damage. Moonlight moth mixes can be used to restore your own Prayer and that of 3 other nearby players fighting the crab, and at lower levels can provide more Prayer restoration than potions. If fighting the crab with a group of friends, or multiple of your own accounts, the moths can be coordinated to maximise their effectiveness across the recipients of the restoration.
  • If using prayer potions, bring a Holy wrench or other items which share its effect.
  • If only using the lowest tier of Prayers, it can be more efficient to just restore Prayer at the altar in Tal Teklan, as it would only need to be done every 5-10 crabs.
• (Optional) A special attack weapon, such as the dragon claws or dragon dagger to use up special attack energy for bonus damage.
  • A defender will be beneficial if using a two-handed main weapon with a one-handed special attack weapon. Ideally a dragon or Avernic defender.
  • If looking to conserve supplies or not worry about using special attacks frequently, using a Dragon battleaxe special attack at the start of each new crab fight can replace the need for Strength potions.
• (Optional) a pickaxe, to mine the boss after defeat and loot a gem.
  • A Gem bag may be brought to hold additional gems, or simply a chisel to cut them for Crafting experience and then dropped or alched.

While Blowpipe has the highest damage output of any weapon, it’s also much more expensive to use for training. Void ranged or Masori are both effective for training on the gemstone crab. Void will typically perform better, but masori can be purchased right away from the Grand exchange, without needing to be unlocked. Due to the crab’s low defences, the 2-tick attack speed of knives and darts allows for consistent hits, resulting in relatively high idle experience close to that of the blowpipe when paired with a high ranged strength shield like the twisted buckler. Rune knives and darts relatively low cost and good DPS make them the most cost effective means of training usually.

1.  Costs between 361,400gp and 1,105,400gp per hour. Amethyst darts in the blowpipe cost 575,000gp per hour if using Ava’s assembler
2.  Cheaper and superior with void, cost efficient
3.  Held in hand, slightly superior with masori
4.  Cost efficient. Darts and knives cost between 4,800gp and 29,400gp per hour to fire with an Ava’s assembler
5.  With Ruby bolts (e). Will only deal 66 damage rather than 110

Due to the crab’s low defence, ranged accuracy is not very impactful, and faster weapons like darts and throwing knives excel here. However, when the adamant crossbow is unlocked at 46 Ranged, it is strongly recommended to consider using it with ruby bolts (e) due to the passive effect which allows players to hit up to 60 on the crab at the cost of some of their current hitpoints. Although this can never kill the player, it is recommended to keep distance from the crab to avoid taking damage from it also. Bringing some food just in case and using Rapid heal can also offset the damage taken. The usefulness of offensive prayers will vary depending on the specific weapon used, and the Ranged level you are currently at, as whether a max hit is gained from activating prayers is not consistent until higher levels, unlike melee. If using a standard Ranging potion, it will usually be worthwhile to have Sharp eye or Hawk eye enabled, as while the buff decays over time you will pass over some level thresholds where the prayers increase damage.

The atlatl is very potent for training Ranged if you have already trained Strength quite a bit past it, and can compete with rune knives or darts with much cheaper accompanying armour. The hunter’s spear functions similarly, and although it is much worse it can still outperform other available options closer to level 55 Ranged, when it is unlocked.

Ranged inventory

• Ranging potions, Divine ranging potions, or Lizardkickers
  • If using the Eclipse atlatl or hunter’s spear, also bring Super strength potions, or instead use special attack energy with the Dragon battleaxe.
• Teleport to the crab, such as a Pendant of ates, quetzal whistle, or runes for Civitas illa Fortis Teleport
• Food, especially if using ruby bolts (e)
• (Optional) Prayer restoring items such as prayer potions or Moonlight moth mixes, if not using the altar in Tal Teklan
• (Optional) A special attack weapon, such as the magic shortbow (i)
• (Optional) a pickaxe, to mine the boss after defeat and loot a gem.
  • A Gem bag may be brought to hold additional gems, or simply a chisel to cut them for Crafting experience and then dropped or alched.

Low level magic is different to many of the other sets in that magic accuracy bonus increases accuracy significantly, magnifying damage and therefore experience rates. The reduction in experience at the gemstone crab along with the lack of an elemental weakness means that, at very low levels, the experience simply isn’t as good as many other options. For exmple, rock crabs have a 20% elemental weakness to earth spells, and allow the player to idle for 10 minutes at a time with a quick reset in between (the same as the gemstone crab). For even faster experience rates, the player may safespot fire giants with water spells, or ice giants with fire spells, for a 100% damage and accuracy increase.

Recommended equipment for magic

Slot	Item (most effective → least effective)
	Elder chaos hood > Xerician hat / Wizard hat
	Amulet of magic / Amulet of glory
	Ardougne cloak 1
	Elder chaos top > Xerician top / Black robe
	Elder chaos robe > Xerician robe / Zamorak monk bottom
	Elemental staves
	Elemental shield
	Unholy blessing
	Chaos gauntlets
	Aranea boots
	Seers ring (i)

Void knight magic equipment is a strong option at mid levels, offering a 5% magic damage bonus alongside increased accuracy; however obtaining the set requires a significant time investment. Alternatively, Elder chaos robes provide a 3% magic damage bonus (1% per piece) in addition to solid accuracy, and require only 40 Magic and 1 Defence, making them more accessible.

While training melee, the player can cast spells. High Level alchemy is the most accessible spell, and can be cast in between melee hits. This does take a lot of effort, but can be done without losing any ticks. Alching yew longbows profits  119gp per cast, granting the player an additional  59,500gp per hour along with 32,500 magic experience per hour. Additionally, the player can cast magic imbue on the Lunar spellbook. This can give passive magic experience at a cost of  190 per cast. Magic imbue costs the player  2.21gp/xp. The spell, granting 86 experience every 12.6 seconds, adds an additional 8,600 magic experience per hour to the players total experience without taking much effort.

Similar to Yama, players who die fighting the Doom are sent back to the lobby area instead of their respawn point, where their graves are also located. Players will have their reclamation fee reduced by 75% until they have 20 total delves, after which the standard death cost will apply.

Requirements

• Completion of  The Final Dawn

Recommendations

• Completion of  While Guthix Sleeps for access to the scorching bow, as there are no other demonbane ranged weapons
  • Holy water is usable for demonic range larvae, but not for disrupting charges in shield phase, and is also extremely tedious to mass produce.
• Completion of  A Kingdom Divided for access to Yama; having unlocked double Death Charge via the rite of vile transference is helpful.
• Completion of  Hard Western Provinces Diary for access to elite void and the crystal halberd
•  90+ Ranged
•  43 Prayer minimum for access to all three protection prayers.
  •  62 Prayer to unlock and use Deadeye.
  •  74 Prayer and  70 Defence to unlock and use Rigour. Highly Recommended.
•  75 Agility for the pit jump shortcut in the ruins.

Transportation

• The Mokhaiotl waystone is a single use item that teleports players to the centre of the ruins, just south of the pit jump shortcut.
• The pendant of ates teleport to Kastori takes players south-east of the lift platform that takes players just south of the entrance to Mokhaiotl.
• The Quetzal Transport System can also be used to travel to near the boss.
  • Tal Teklan – West of the lift to the boss, a bank is available in town.
  • Kastori – South-east of the lift to the boss, no bank available.

West of the lift platform underground, a chest can be opened to obtain two ancient teleporters, which can be used to speed up the run north to the entrance to Mokhaiotl. It is optimal to place the initial teleporter a tile or two north of the lift platform, then placing the destination teleporter adjacent to the door to skip the delay before entering the door after teleporting.

Fight overview

As a delve boss, defeating the Doom will cause it to delve deeper into the archive, growing in power as it does so. Pursuing it into deeper delve levels will increase the difficulty of the fight, up to delve level 8.

Upon starting a delve run, the Doom of Mokhaiotl starts with a combat level of 558 and 525 Hitpoints. For every delve level after – up to delve level 8 – it will gain 50 additional combat levels and 25 Hitpoints. This excludes delve levels 6 and 7, which both have 650 Hitpoints. The boss’ stats remain identical across delve levels, though the damage it deals continues to increase.

The Doom will not appear until the player clicks out of the prompt (jumping through the gap or descending down a level), after which it will spawn shortly afterwards.

The Doom possesses a Defence level of 90 and Magic level of 275. It possesses +300 stab and slash defence, +60 crush defence, and +160 magic and overall ranged defence. Additionally, the Doom has a defence drain cap of 30, meaning that its Defence can only be lowered to a minimum of 60. It is not immune to poison, with any hits that would inflict venom instead being converted to poison.

Further delve levels – referred to as deep delves – will remain at the same difficulty as delve level 8 in theory (having 625 Hitpoints instead of 675), but the persistent acid blood that remains in the arena makes it practically more difficult, in addition to reduced amounts of rocks generated after the end of the blue shield phase, offering less safespots against the car slam attack.

Mechanics

The Doom’s standard attack consists of a single projectile, with its colour and shape indicating the combat style to pray against: blue for magic, green for ranged, and red for melee; melee-style projectiles will begin being used at delve level 2 and beyond. These attacks will calculate damage on impact and as such can be protected against after the Doom launches the projectile. If the player does not activate their protection prayer in time, they can deal up to 47 damage, gradually increasing as the delve level increases; at level 8, a missed projectile can deal up to 65 damage. The speed of these projectiles is rather slow at the first few delve levels, but will increase until delve 6, where they are at their fastest.

Additionally, standing next to the Doom will result in a melee attack in which it whips the player with its tongue, dealing up to 40 damage, halved if Protect from Melee is active.

The Doom additionally has a multitude of special attacks and hazards that it will use depending on delve level, and higher delve levels will enhance these as well as require the player to react to multiple at once.

Demonic larva

Occasionally, demonic larvae will drop from the ceiling and begin moving towards the Doom. These larvae will always spawn around the player’s position.

If a larva reaches the very centre of the Doom, it will heal it and damage the player, as well as gaining one stack of “demonic charge”. This initially starts at 10 health healed and 1 damage dealt, but additional stacks of demonic charge will increase the amount the Doom heals and the damage the player takes. Demonic stacks are not reset between delve levels, so it is important to kill the demonic larvae when the opportunity allows.

Demonic larvae have 2 Hitpoints and can only be one-shot by demonbane weapons, multi-hit weapons, and the Eye of Ayak; any other weapon will only deal 1 damage, requiring two attacks to kill one. Demonbane weapons also have the added benefit of not incurring attack delays, allowing players to immediately attack it and the Doom without delay.

When demonic larvae are killed, they will explode and deal up to 21 damage in a 3×3 area; however, if this hits the Doom, it will deal 5-10 damage (or 100 shield damage) instead, and the player will not take any damage from the explosion.

The demonic larvae will begin to increase in intensity as the delve level increases:

• At delve levels 1-3, they will have a random protection prayer active.
• At delve levels 4+, they will have two protection prayers active, with their colour indicating which combat style to use: blue for magic, green for ranged, and red for melee. Melee demonic larvae will only appear during the shield phase.
• At delve levels 5+, two can spawn at the same time outside of the shield phase.
• At delve levels 8+, a giant demonic ranged/magic larva can spawn outside of the shield phase. These larvae have doubled health, have a 4×4 AoE explosion around itself and tripled penalties if allowed to reach the Doom; e.g a missed large larvae, at 0 charge stacks, will heal Doom for 30 hitpoints and deal 3 damage to the player.

Larvae will despawn after ~20 or so seconds have passed after spawning, however this only occurs when Doom has repositioned itself during the car phase. They will always be able to reach Doom otherwise.

Rock Throw

The Doom launches a large rock into the air, exploding into multiple falling rocks that target the area where the player stood, indicated by looming shadows. One will always land on the tile the player stood on at the time it exploded, which will remain in place as a rock, while the others do not. Running into a shadow will result in the player taking 15-20 damage. If the player does not move from their initial tile at the time of explosion, the resulting rock will shove the player away to a random valid tile in a 3×3 radius surrounding it.

Immediately after the large rock explodes, the player’s protection prayers are disabled. The colour of the rock determines what attack is used first; if it is a normal rock, then the first hit is always ranged. If the rock is glowing blue, then the first hit will be magic. Melee projectiles are never used with these rocks.

The rock throw attack will increase in intensity as the delve level increases:

• At delve level 1, only one projectile is launched.
• At delve levels 2 and 3, two projectiles are launched, with the second landing one tick after the first.
  • The projectiles will never repeat in a row (i.e. a ranged projectile will always be followed up with a magic projectile and vice versa)
• At delve levels 4+, three projectiles are launched, and often in sync with Doom’s attacks that the player will be hit four times in four ticks.
• At delve level 7, the projectiles will reach the player 2 ticks (1.2s) after the rock explodes.
• At delve level 8, two rock throws are performed, which will always be identical.
  • To avoid damage from the attack, the player must pray after the second rock explodes; projectiles from the first rock will not appear until this occurs.
  • The looming shadows from the second rock will never overlap with the first’s; with precise timing, the player can utilise the looming shadows generated by the first rock to use as safe spots against the second.
  • It is also important to try to time Doom’s attacks, especially whilst it is charging so that its standard attack doesn’t overlap with the last attack of the second rock.

Special Beam Cannon

The Doom enters a defensive stance and begins to charge up, indicated by a yellow charge bar appearing. If allowed to charge completely, the Doom will unleash the Special Beam Cannon, dealing 60 damage. If this is performed as a standard charge, it will additionally heal 300 hitpoints. This increases to 80 at delves level 3-5, and deals 99 damage at delve level 6+. This makes it the highest priority attack to deal with, as the Doom will also charge faster at higher delve levels.

There are three distinct occasions in which the charge bar appears, and the player must attack the Doom to interrupt/reset the charge bar. Attacks whilst charging are 100% accurate and will always result in a successful hit.

• Standard Charge – on all delve levels, the Doom will pray against ranged and magic () and begin charging. This is always accompanied by the Rock Throw attack. Only a melee attack will interrupt the charge.
• Shield Charge – at delve levels 3+, the Doom will begin using a demonic shield with 500 shield health and begin charging constantly. Only demonbane weapons (excluding holy water) will reset the charge.
• Car Charge – At delve levels 5+, the Doom’s burrowed form (commonly referred to as “car phase”) will always be charging constantly. Any attack will reset the charge.

Melee punish

Whenever the Doom begins a standard charge, only a melee attack will interrupt the charge, which will also deal bonus damage that deals ⌊15S⌋ damage, where S is the player’s visible Strength bonus. As such, offensive prayers and set bonuses (such as Void Knight equipment) will not increase the bonus damage. When using multi-hit weapons such as the dual macuahuitl or earthbound tecpatl, the bonus damage duplicates itself once per hitsplat.

The Doom’s next attack is additionally delayed by several ticks if melee punished; this starts with a 8 tick delay at delves 1 and 2, 7 ticks at delves 3-6, and 6 ticks at delves 7+. Using a 5 tick weapon, such a scythe of vitur or noxious halberd, will always allow for the player to get a hit in with their ranged weapon before the Doom resumes its attack rotation.

Additionally, if the Doom is defeated by a melee punish, projectiles resembling holy water will be launched around it, restoring 28 Hitpoints, 14 prayer points, and 25% special attack energy, as well as clearing up acid blood in a 3×3 area around the projectile’s landing tile. This can only be done at delve levels 1-8; delve levels beyond 8 will not trigger this mechanic.

Shockwave

Generally performed around a minute into the fight, this attack is indicated by the multitudes of volatile earth spawning in the area. 20 ticks (12s) after they appear, the Doom will initiate its shockwave attack, dealing 30-40 damage per shockwave. This equates to three attacks from the Doom before this occurs, and one of these will always be a Rock Throw. If an auto-attack is used as the last attack, it will be partially cut off by the shockwave animation.

To protect against the shockwave, the player must attack two volatile earth (which does not incur attack delay) to generate an earthen shield, then stand within it for protection. Notably, despite having 1 Hitpoint, the player in actuality deals damage equal to their max hit, meaning health or prayer restoring special attacks such as the toxic blowpipe and eldritch nightmare staff should be used to attack volatile earth to maximise restoration if necessary.

The first volatile earth destroyed determines the destination of the shield, while the second determines its spawn point. Additionally, the shield will move at walking speed, prioritizing diagonal movement before moving straight towards its destination. The centre tile of the shield will also remove acid blood if present in its path.

The earthen shield will dissipate upon reaching its destination or when the Doom’s shockwaves end, whichever happens first. As such, players must get the timing right for spawning the earthen shield as well as pick two points far enough apart to last the entire attack. Keep these in mind when deciding where to stop and start the shield path, using the shield to remove acid blood and avoiding rocks that will block the player’s path.

The shockwave attack will increase in intensity as the delve level increases:

• At delve levels 1 and 2, there will be only one shockwave.
• At delve levels 3 and 4, there will be two shockwaves, occurring two ticks in between.
• At delve levels 5 and 6, there will be three shockwaves.
• At delve level 7, there will be four shockwaves.
• At delve levels 8+, there will be five shockwaves.

With top-end gear, the player may occasionally defeat the Doom right as the volatile earth spawn in. In these cases, it is recommended to quickly destroy a pair to create a path that would clear the most acid blood before descending further, as they will only remain for a short duration before all of them despawn upon the Doom’s defeat.

Acid blood

Starting at delve level 3, the Doom will begin to spray acid blood in a square-shaped area surrounding it, choosing a random cardinal direction to spray, which will inflict up to 6 venom damage per tick if stood on. It will spray 2-3 acid blood whenever it is damaged outside of its shield or car phase; this includes hits from thralls and multi-hit weapons. As such, players should be mindful of using thralls and multi-hit weapons such as a crystal halberd or scythe of vitur if going deep down.

Acid bloods are carried over between delve levels, with the exception of delve level 6, where reaching it will wipe the entire area clear for one time only. The only other ways to clear acid blood after delve level 6 is to trigger holy water projectiles (until delve 8), or the use of the earthen shield’s central tile.

At delve levels 5+, players can manipulate the Doom during the car phase into the direction where it splatters acid, simply causing it to pile up on the wall without repercussions.

Demonic shield

Starting at delve level 3, the Doom will start initiating a shield phase with 500 shield health and begin charging constantly for its Special Beam Cannon. It will usually attempt to do so upon reaching 75% health, after two attacks (unless it was preparing a Standard Charge), giving a small leeway for an additional attack before it enters this phase.

As the Doom does not change appearances, there are a number of ways to determine whether it has started this:

• If the in-game setting “Show boss health overlay” has been enabled, the health bar will change from green to blue.
• When the Doom’s name is changed to “Doom of Mokhaiotl (Shielded)”
• The appearance of a blue health bar or a purple game message stating The demonic shield resists your attack!
• Use of a RuneLite plugin

If an attack was launched during the transition from actual health to the shield phase, it will deal actual damage to the Doom if it lands before the shield is set up. If the shield is set up and the attack lands shortly afterwards, it will damage the shield instead.

The Doom’s shield can only be harmed with demonbane weapons (excluding holy water), which have 100% accuracy and will also reset the charge bar; as such, the Doom must be attacked every now and then to interrupt the charge. Additionally, demonic larvae will continuously spawn from one direction and move towards the Doom, usually from the southwest, west, northwest or north, rather than around the player. If these are not available due to a wall blocking the way, they will spawn in other directions. During the shield phase, exploding larvae will deal 100 shield damage to speed things up considerably, especially at higher delve levels when the rate of spawning larvae increase.

Be sure to stay out of melee distance from the Doom before the shield phase ends before delve level 5, as Doom will immediately resume attacking, which can often result in a melee attack without any animation.

At delve levels 5+, the Doom will always initiate the shield phase after two attacks from the last shockwave in sequence.

Burrowing (car phase)

Popularly known as the “car phase”. Starting at delve level 5, after the shield phase ends, the Doom will enter a burrowed form and cause numerous rocks to fall from above. During this transition, there is a short grace period in which players can run over acid blood and stand in larva explosions without consequence.

Once burrowed, the Doom checks which of the 8 compass directions the player is located in relative to its center, then spawns a yellow eye four tiles past the player in that direction. After a short duration, the Doom will zoom straight towards the eye, destroying any rocks and trampling players in the way, before doing so a second time. After two zooms, the Doom will return to its regular form and initiate the countdown for the shockwave attack.

During the car phase, the Doom will be charging constantly for its Special Beam Cannon, making it an opportune time to use a Zaryte crossbow or dragon knife special attack as all attacks made whilst charging are 100% accurate. Any attack will reset the charge.

The car phase will increase in intensity as the delve level increases:

• At delve level 5, the Doom will zoom twice, and trample damage dealt is at 10.
• At delve level 6, the Doom will zoom, launch 1-3 standard attacks depending on distance travelled, then initiate a Car Slam attack. It will do this three times. Trample damage is also increased to 20.
  • Instead of an earthen shield, the rocks that fall when it begins burrowing serve as protection from its slams.
• At delve level 7, trample damage is increased to 40.
• At delve level 8, the zoom speed is significantly increased.
• At delve levels 8+, there will be fewer falling rocks provided for the player to protect against its Car Slam.

Rockblock

At delve levels 6 and above, the Doom will utilise Car Slams, destroying every rock within 15 tiles from its centre tile, excluding rocks that were protected by another rock. As such, players must be mindful about where they lure the Doom to, lest they have it destroy a set of rocks that the player intended to use in a subsequent Car Slam. This is especially the case at delve levels 8+ when fewer rocks will fall when it burrows.

With some planning, players may use rocks that are placed from Rock Throw attacks to their advantage by standing on specific tiles as the rock explodes, then luring the Doom towards it so that its centre tile is right where a rock is. When the Doom performs a Car Slam, that rock will fully block it and result in no rocks (besides itself) crumbling for that Car Slam. This is known as “Rockblock”.

There are multiple ways to execute Rockblock. With the tile markers provided, players should stand on the green tile in the north or east side and wait until the Doom uses a Rock Throw. When the rock begins to dip down (one tick before it explodes), running towards the white/pink tiles will always place the rock at tile the player stood on and put them outside of the 9×9 debris field. This makes it useful to avoid the looming shadows from a rock throw, and at delve levels 8+ allows the player to commit more focus on praying and dodging the second rock throw.

When the Doom uses another Rock Throw, place the rock around the purple tile labeled “3” if possible; otherwise, the white/pink tiles will suffice. Players may damage the boss too quickly for it to use a second Rock Throw in delve levels 6 or 7, in which case players may have to hold back on proccing shield phase until it does or hope that the start of the car phase will put falling rocks in a favourable position.

Once the car phase starts, keep attacking the Doom whilst doing the following:

1. Stand by the gold tile labeled “1” until the Doom’s eye appears over it.
2. Move to the cyan tile labeled “2” until the Doom’s eye appears again, using the rocks placed around the aforementioned area to protect against the second slam. Doing these first two steps correctly should preserve a sufficient amount of rocks in the south-western area.
3. Stand around the purple tile labeled “3”. If the player is able, standing beyond the row of three purple tiles labeled “3t” will cause the Doom to move for one extra tick, which can sometimes be enough to squeeze in one more attack.

Attack rotations

During delve levels 1-4, the Doom uses standard attacks, charges with protection prayers, exploding ball, and shockwave attack in its rotation. Shockwave attacks during these delves begin after roughly one minute has elapsed on that delve level.

During delves 5 and higher, the attack rotation is slightly changed due to the addition of a new phase type:

• Standard delve 1-4 attack rotation
• Blue shield (upon reaching 75% of its health)
• 2 Car attacks
• Earthen Shield
• 3 auto-attacks
• Shockwave
• 2 auto-attacks, of which one will always be an exploding rock
• Loops back to blue shield

After delve 6, the attack rotation would always be as follows:

• Standard delve 1-4 attack rotation
• Blue shield (upon reaching 75% of its health)
• Car + 1-3 auto-attacks
• Slam
• Car + 1-3 auto-attacks
• Slam
• Car + 1-3 auto attacks
• Slam
• Earthen Shield
• 3 auto-attacks, of which one is guaranteed to be an explosive rock
• Shockwave
• 2 auto-attacks, of which one is guaranteed to be an explosive rock
• Loops to blue shield

Table of attacks by delve level

Equipment

While the Doom is weakest to crush attacks, the fight has many mechanics which make melee unfriendly, especially at deeper delves. Players are instead recommended to use ranged despite its higher defence bonuses, as its low Defence level somewhat offsets them; the twisted bow is the best weapon to use due to its 275 Magic, while the scorching bow is a slightly weaker, but still powerful alternative.

Special attack weapons

The Zaryte crossbow is the most powerful special attack weapon and should be paired with regular enchanted ruby bolts for cost efficiency, as the dragon variant provides no additional benefit in this scenario. When to use it will vary – at delve levels 1-4, a successful special attack can help speed up the fight and reach deeper quicker. However, at delve levels 6+, it is not recommended to use the crossbow special attack as the opener due to the necessity of the Rockblock strategy at higher delve levels. As such, it is recommended to use the crossbow special attack once the car phase starts to guarantee a high successful hit (as all attacks are 100% accurate in that form), or if health/supplies are low, preserve energy for a special attack that restores hitpoints or prayer on the volatile earth (ex. a toxic blowpipe) for a large amount of restoration.

For players who do not have a Zaryte crossbow, their next best option is to use a crystal halberd, reserved for melee punish. Every melee punish with a crystal halberd will guarantee a minimum of 46 damage (two bonus hits of 23). This is the same guaranteed damage as a Scythe of vitur would deal (three bonus hits of 15). The additional range, much higher average upfront hit, and availability to all players makes the crystal halberd much more desirable than even the scythe on depths 6+. Bringing extra switches for melee punish is not necessary given its randomness, but players who wish to do so are encouraged to bring the best melee amulet and gloves. This will increase death costs, so players are not recommended to bring these swaps unless they are already repaying the highest amount possible.

Dragon thrownaxe special attacks are a popular alternative to Dragon knife special attacks as they give only a slight loss of damage whilst using half of the ammo per spec and costing significantly less, 473 and 21,705 respectively. This totals a difference of 34,349.60 per 4 special attacks used when wearing an Ava’s device, losing only 3 max hits in Masori armour with a Twisted bow and 27 max hits in budget Elite Void Knight equipment with the Scorching bow cumulatively across the 4 special attacks.

Immediately when car phase starts, use a Zaryte crossbow special or dump 3-4 dragon knife special attacks. For dragon thrownaxes – use your bow initially, and when safe to do so, you can switch to thrownaxes on the tick after you fire and dump your specials, utilising their attack reset mechanic. If these are not available, a toxic blowpipe with the best darts can deal reasonable damage. Note that at deeper delves, these short-ranged weapons are likely to have diminishing returns unless the player is able to manipulate Doom and attacking from a safe distance. Phasing deep past 75% health and starting car phase with a Zaryte crossbow special, or dragon thrownaxe/knife dump, will make it much more likely that the boss dies before it gets the chance to pull off a shockwave attack, as it and exploding rocks have a very high chance of death if handled improperly.

Due to the importance of special attacks on key phases of the fight, a lightbearer is highly recommended over any other ring. Upgraded Death Charge from Yama is extremely beneficial as well, as Death Charge procs on both Doom and its larvae. With upgraded death charge and a lightbearer, you can restore 40-50% energy per level. Similarly to Fortis Colosseum, special attack energy is only restored while fighting the boss from scratch; e.g if a player defeated the Doom 3 seconds before their energy restores and descends before the energy is restored, players will not be restored that energy and have to wait for a full reset.

While a defence-draining weapon such as the Tonalztics of ralos, dragon warhammer, or elder maul can improve accuracy, the Doom’s defence cap, relatively low hitpoints, and guaranteed accuracy during the melee punish and car phase make them less helpful than expected. If you factor in guaranteed damage from demonic larvae, melee punishes, and car phase, defence-draining weapons can often increase the average time to kill.

Players with low combat stats, ironmen without a Zaryte crossbow or dragon knives/thrownaxes, or players struggling to get many attacks in during car phase can use any of the mentioned defence-reducing special attacks at the start of the fight. Although generally slower, you will still gain additional consistency of attacks leading up to the volatile earth shockwave while still retaining special attack for melee punishes.

Summary

Best in slot:

• Bring a Zaryte crossbow, scythe, and crystal halberd.
• On 1-4, immediately crossbow spec. Use scythe for punishes.
• On 5-8+, do not immediately crossbow spec. Use the halberd spec on melee punish attacks.
• When car phase starts, crossbow spec as your first attack.

Budget:

• Bring dragon knives and a crystal halberd.
• On all phases, use halberd spec on melee punishes.
• When car phase starts, use your bow until you can safely use as many dragon thrownaxe specials as you have the tick after, trying to maximise their attack reset mechanic.
• Toxic blowpipe spec can restore the maximum health possible on volatile earth if deemed necessary.

Masori vs Elite void

Players have the option of choosing between Elite Void Knight equipment or fortified masori against the Doom. Both give a very similar performance, but there are various factors that can influence the gear used.

When using a scorching bow as a primary, elite void is recommended, as the 4-tick speed, the Doom being susceptible to demonbane, and being able to use dragon arrows helps alleviate accuracy issues during the fight. Additionally, elite void has very low reclaim cost, allowing players to focus on upgrading other slots and minimising death costs. While the accuracy bonus is not as impressive as masori, elite void provides a higher max hit. This is especially useful after delve level 5+, where there are many phases that provide 100% accuracy.

When using a twisted bow as a primary, fortified masori is recommended for more accuracy to help the twisted bow’s accuracy, increasing the chances of overall high hits, especially during phases where accuracy is not 100%. However, it deals slightly less damage than elite void, especially when 100% accuracy is guaranteed. The defence bonus of fortified masori slightly helps in reducing the chances of Doom’s attacks hitting by ~12%, but can be quite expensive which will result in high reclaim costs upon death, which can be detrimental if the player dies frequently. As such, it is only recommended for very experienced delvers.

Spellbook choice

If using the Eye of Ayak, players may choose to use the Lunar spellbook with Vengeance and possibly Spellbook Swap for Death Charge, though keep in mind the Eye will not disrupt the Doom’s shield phase charging.

If not using the eye, players should stay on the Arceuus spellbook, with runes for Death Charge. Ward of Arceuus is optional, as it weakens the Doom’s auto-attacks, but has no effect on any of its other attacks. Thralls are not recommended for the fight, as their attacks will cause more tiles to be ragged by acid blood, and they have very little uptime; they will not attack Doom during shield phase, and car phase usually doesn’t last long enough to justify their damage.

Masori equipment is the best equipment when combined with a Twisted bow for normal attacks on The Doom. Elite void ranged is comparable with masori after defence reductions, is much cheaper, and is better overall when used with the Scorching bow. Additionally, certain phases beyond delve level 5 make attacks 100% accurate, benefitting elite void immensely. Additionally, there are certain pieces of equipment that gain additional strength bonus towards melee punishes without losing much ranged damage, such as Aranea boots or Barrows gloves.

Slot	Recommended equipment for Ranged – Item (most effective → least effective)
	Masori mask (f) / Void ranger helm[a]	Masori mask	Serpentine helm
	Necklace of anguish	Amulet of blood fury	N/A
	Dizana’s quiver	Ava’s assembler	N/A
	Masori body (f) / Elite void top[a]	Masori body	N/A
	Masori chaps (f) / Elite void robe[a]	Masori chaps	N/A
	Twisted bow	Scorching bow	Toxic blowpipe[b]
	Dragon arrow[c] + Ruby bolts (e)	Amethyst arrow[c] + Ruby bolts (e)	N/A
	Zaryte vambraces / Void knight gloves[a]	Barrows gloves	N/A
	Avernic treads (max)	Pegasian boots / Aranea boots	Blessed boots / Mixed hide boots
	Lightbearer	Venator ring	Ring of suffering (i)
	Zaryte crossbow / Dragon knife[b]	Dragon thrownaxe[b] / Tonalztics of ralos	Elder maul > Dragon warhammer

1.  Only when using full Void Knight equipment.
2.  Best used on 100% accurate car phase.
3.  Can be poisoned for extra effect

In addition to the demonbane weapon to disrupt the blue shield, it is faster to bring a one way demonbane or multi-hit swap for each style to deal with larvae. Emberlight is a marginal upgrade over Arclight/Darklight/Silverlight if used for the melee punish, as it is primarily used for 1-shotting larvae. A staff that can auto-cast demonbane spells is very convenient due to the rapid switches between styles. A cheaper staff like the Slayer’s staff should be preferred to reduce death costs. Superior Demonbane can be used on autocast instead of Dark Demonbane so that magic demonic larvae can be dealt with even after drinking brews, as two sips of brew will prevent players from autocasting Dark Demonbane.

Slot	Recommended equipment for clearing Demonic larvae – Item (most effective → least effective)
	Darklight and other variants[a]	Burning claws	Sulphur blades / Glacial temotli / Earthbound tecpatl	Dual macuahuitl[b]
	Eye of ayak[c]	Any staff that can autocast demonbane spells	Any powered staff	N/A
	Scorching bow	Holy water	N/A	N/A

1.  Using Emberlight increases your death cost for no significant gain.
2.  The second hitsplat is delayed and kills the larva one tick later. This will cause you to attack a second time if not clicking away immediately after attacking, potentially dragging you into venom or other hazards.
3.  It is recommended to charge the Eye with demon tears, as this causes it to passively gain charges upon defeating the Doom and thus incur no charging costs.

It is also very worth bringing a multi-hit melee weapon for the melee punish attack (explained above). Bringing additional strength bonus gear can be worth it to increase your bonus damage, but learners should not replace food to bring strength bonus beyond just the weapon. Do not bring void melee helm or a super combat potion, they will not increase bonus damage. Activating piety will help marginally with the damage of the initial hit, but provide no bonus to the bonus hit, as nothing will increase the bonus damage except for strength bonus.

Slot	Recommended equipment for Melee punish – Item (most effective → least effective)
	Scythe of vitur	Noxious halberd[a]	Dual macuahuitl or other multi-hit melee weapons	Darklight or its variants[b]
	Crystal halberd[c]	Dragon claws[d]	N/A	N/A

1.  Noxious halberd’s average hit is about half of that of the crystal halberd spec. It can be considered for deep delves to spawn less acid.
2.  While normally effective on demons, has a very low base strength bonus. Can be used in a pinch to interrupt the charge beam, but will miss out on significant amounts of free damage.
3.  Special attack should be used as long as it will not interfere with a zcb spec.
4.  Dragon claws paired with at least 25 strength bonus can beat Crystal halberd, but as a 4 tick attack it is much harder to use, especially while dodging mechanics.

Inventory setups – Max Ranged

If the player doesn’t have dizana’s quiver, the empty inventory spot should be replaced with ammo. Crystal halberd is only useful for players who do not have a zaryte crossbow, as it is not possible to get a crossbow spec every kill if using in conjunction with halberd specs.

Inventory setups – Budget

Plugins

All of the following plugins are available on both officially approved third-party Game clients. On RuneLite they must be installed separately from the Plugin Hub, accessed from the Configuration button (wrench icon on sidebar), then clicking the Plugin Hub button (right-most plug icon). On HDOS these plugins come preinstalled.

Better NPC Highlight

• Check “Highlight Menu Names” at the bottom of the plugin settings
• For Demonic Larvae at delve level 4+, and Giant Demonic Larvae at delve level 8+: Paste 14711:2,14713:1,14712:5,14788:2,14789:5, to Hull or True Tile IDs
• To distinguish regular Doom and shielded doom: Add *mokhaiotl:1, *mokhaiotl (shielded):5 to Tile -> Tile Names
• For true tiles of burrowed Doom and the earthen shield: Paste 14709,14715:5 to True Tile -> True Tile IDs

Custom Menu Swaps

• To have the demonic larvae attack options appear on top of anything else: Add Attack,demonic*larva* to “Custom Swaps”

Visual Metronome

• Visual Metronome checked, ‘Tick Count’ set to 20
• Set Hotkey Settings > Tick Cycle Reset Hotkey to any comfortable key, and Reset to Tick to 0
• Press the hotkey when the Volatile Earth spawns, the boss will begin the shockwave attack when the timer hits 20.

Radius Markers

Radius Markers (found in the sidebar after installation) can be used to outline specific attack ranges from the Doom, to enable safe drag attacks with a halberd. Copy the below import and then click the import icon, which will add a 4-width floor outline around Doom, and meleeing Doom with a halberd while on the inner edge of the line will always safely not drag you into melee distance. Additionally, this marker will change from blue to green when the Doom initiates their shield phase, so that you do not mistakenly attack with a halberd and cause a long attack delay.
