Thralls are summoned allies from the Arceuus spellbook, cast with the Book of the Dead. Gnomonkey treats them as a nearly universal source of damage: the key to any challenge run is using thralls always, because they deal a lot of damage while his own damage is low.9 He calls them really important for Olm1 and often uses them in Tombs of Amascut, where he keeps the Book of the Dead as an offhand switch.5
Damage and value
A thrall hits 0 to 3 (average 1.5) every 4 ticks, adding about 0.625 DPS.4 He repeats the figure as 0.625 DPS on every boss, around two thirds of a DPS, which speeds up a raid by several minutes, especially with weaker gear.5 In 2025 he says thralls are always 0.6 DPS, roughly a 15% DPS increase for Sardaco's gear, and that the lower the gear, the bigger the share.6 In a Tombs of Amascut raid they save one to two minutes10 and added about 2k extra damage in one run because everything in the raid is very tanky; with 4 DPS from a player, 0.6 of it is the thrall, which is bigger than a weapon upgrade.11 Thralls never miss: they roll zero to three damage every hit, ignore defence and just punch through.12
His own damage can still exceed a thrall's: he states he somehow does more DPS to Jad than a thrall, noting a thrall costs 10 fire runes while Undead Grasp costs 12 per cast.7 He disagrees with a Reddit post comparing thralls to Surge potions as something you lose DPS without; Surge potions are not the same.13 In a September 2025 competitive raid the group voted to allow thralls and the Book of the Dead over one objection14; players noted that during Kephri the only damage being done was through thralls and told everyone to re-thrall15, and his thralls probably did about half of his damage, which affected how the top score was viewed.16
In the Colosseum, he found waves became easy once he switched to thralls, which provide so much DPS that Ancients is not the play.17 He pulled soul runes from his Shadow for Death Charge to keep SGS specs going18, and notes that everything there has high magic defence, and SGS plus Bloodfury gives the same sustain as camping Death Charge.17 He chose thralls over Barrage in the mage-only Fight Caves because they out-damaged his own casts on high-mage-defence monsters.19
Choosing a type
- Zombie (melee): often wastes ticks walking around, so he typically avoids it2, but he summons it for the last phase of Akkha20 and for Theatre of Blood phase 1 (otherwise damage is reduced).21
- Skeleton and ghost: effectively the same, both with a range of six tiles.2
- Where a monster has high defence but is not invulnerable to a style, such as the Dagannoth Kings or the Kalphite Queen, thrall style does not matter and full damage goes through.2
- At Callisto the mage thrall does nothing because he is invulnerable to magic.22
- Many Chambers of Xeric bosses have flat reductions: the Great Olm's hands and head take 50% less from the wrong style, and a wrong-style thrall's max hit drops to one. Use mage on the mage hand, melee on the melee hand and skeleton (ranged) on the head.223
- Much content forces a type: a mage thrall on Vasa Nistirio (crystals are immune to ranged), a specific type for each hand of Ulm with ranged on its head, and melee at Theatre of Blood P1.21
- At the Ice Demon a thrall maxes one and rarely hits (about one in four hits; a would-be three becomes a one, otherwise a zero), so he does not bother summoning one, though he does not knock others for it.2324
- Chambers is one of the few raids where thralls are not the default spellbook, but they are really good for learning solo Olm25; without one, a zero hit makes Olm turn midway and hit you.26
In Tombs of Amascut he uses Death Charge because many things give it: monkeys at Baba, Kephri's swarms and adds, Akkha's shadows and the core on Warden P2. He runs no Blood Barrage in the Atlatl setup because thralls and Death Charge give more specs and DPS.1010 Thrall monkeys in Ba-Ba's room also drink prayer.27 For Nex he brings runes for Death Charge and thralls, since thralls hit through Nex's very high defence; see Nex gear setup.
The Doom of Mokhaiotl upgrade (2025)
In January 2025 the Doom of Mokhaiotl blog proposed a consumable stored in the ammo slot that makes thralls boomerang back when they despawn and damage the target if they hit.28 Gnomonkey objected that many bosses are in walled areas (Ulm, Warden P3, Duke Sucellus) where a boomerang cannot pass, and some wander (Vasa Nistirio).28 His design principle is that any upgrade must always benefit thralls so the currency has a reason to be used; otherwise players spam the consumable at bosses where the mechanic does not work.29
He assessed community suggestions:
| Suggestion | Opinion |
|---|---|
| Thrall damage 0-3 to 1-3, no thrall book | Always buffs thralls and works as a baseline, but he wants better; the no-book part would be a huge buff.3031 |
| AoE around the thrall | Dislikes it: players do not control the spawn, so a thrall one tile off Kephri misses, forcing re-summoning and more currency.32 |
| Stand-with-thrall buff (e.g. min hit of four) | Would push players to use thralls where they cannot reach (Vespula, Zuk); the buff should apply where thralls are already used.33 |
| User-controlled thrall placement | Likes it, and says the boomerang would work much better with it.34 |
| Typeless thralls with different effects | Appealing, turning the choice into decision-making rather than APM.35 A typeless omni-thrall would reduce complexity.36 |
| Damage over time on all thralls | Adds little; burn is buggy and appears to count as ranged, so it hits zeros on ranged-immune targets.37 |
| Debuff building a DoT on the target | Too complicated: a thrall is summoned and does damage, as Avenge is cast and reflects.38 |
| Exploding thrall or thrall bomb | Too crazy an effect for something that should be simple and small.39 |
He is leaning toward three differentiated types, each doing its own simple thing.40 Thralls are currently set-it-and-forget-it, poor ground for a play-around bonus, and may need a rework.41 A thrall upgrade charging the book of the dead is less clunky than ammo-slot tokens, which he finds really frustrating, and it should charge something even if the book is later removed by a quest.42 He agrees thralls are far less interesting than Vengeance, which involves deciding when to dump health on a target; players almost never take Vengeance outside spellbook swapping in Theatre of Blood and just camp thralls.4344 He suggested on stream that doing something right with a thrall could grant a mini Vengeance or recoil proc, though it would require a rework.45
Jagex then removed the planned upgrade from the rewards.8 He had asked for ideas, got hundreds of comments, and was shocked Jagex dropped the idea instead of using one; he calls dropping the thrall currency and upgrade one of the worst changes he has heard of pre-update.846 A minimal upgrade, he says, would be hitting one to three, or giving thralls different effects and making them typeless.47
