Arceuus spellbook is a mechanic topic that Gnomonkey covers in 5 videos between 2024-03-25 and 2025-07-18. This article is a stub: his statements are grouped by type, repeated ones merged.

Contents

Methods

  • Gnomonkey uses Arceuus for Death Charge, which lets him SGS spec more, since several targets give a guaranteed max hit that heals about 30 health; he says it is for Death Charge more than for thralls.1
  • When a wave has a quartet with two Berserkers, Gnomonkey casts Undead Grasp on the first, then the second, goes behind the pillar, and as each unfreezes and pulls up he casts the Trident to kill it, so he takes no melee hits and does not have to tank.2

Stats and numbers

  • Undead Grasp has a chance to bind enemies in place for four ticks and maxes 24 by default; with Mark of Darkness active and cast before the wave, it is guaranteed to freeze for four ticks.3
  • Thralls from the Arceuus spellbook add a flat 0.625 DPS at any location, which is more DPS than most gear additions and typically 5 to 10% of your total DPS.4

Tips

  • With Arceuus you do not have to bring an extra rune to get both Death Charge and thralls, no matter the setup.1
  • A Shadow is charged with soul runes so you can pull soul runes out for Death Charge, and if you lack a Shadow the Sanguinesti staff has blood runes that can be pulled instead; both carry the runes without wasting a slot.5
  • The Arceuus spellbook also provides thralls, and Gnomonkey combines Mark of Darkness with Undead Grasp; his inventory ends up with Death Charge, thrall, Mark of Darkness and Undead Grasp using a single rune pouch slot.3
  • Undead Grasp is a manually cast spell so Myopia does not affect its range, which is always 10 tiles, and from wave nine on Gnomonkey starts waves with Undead Grasp.6
  • He uses the Arceuus spellbook in the Colosseum because dropping an item lets him pull runes out of his Tumeken's shadow to cast Death Charge and thralls, which add damage and enable more DPS and Saradomin godsword specs.7

Gnomonkey's opinion

  • Gnomonkey thinks the Arceuus spellbook is much better than Ancients in the Colosseum because everything has a very high magic level so you cannot blood barrage them very easily.1
  • Gnomonkey considers the Ancient spellbook complete trolling for Colosseum and recommends the Arceuus spellbook, because Death Charge and the Saradomin godsword give more healing across the run than Blood Barrage would.8
  • Gnomonkey says that despite costing prayer points and an inventory slot for the Book of the Dead, thralls use fewer overall resources than something like Blood Barrage at almost every location.4
  • Gnomonkey says the Colosseum is not like the Inferno, where Blood barrage is needed for health, because specing with the Saradomin godsword gives health back.9
  • Gnomonkey notes a Reddit comment that the new chaos rune cost forces bringing loose chaos runes outside the rune pouch at Yama, and thinks it should be one or two death runes instead, which fit with Death Charge runes.10
  • Gnomonkey says Thrall casting is the main sink for his blood runes on the iron, and thinks moving the cost to soul runes evens things out, though Death Charge still needs a soul rune and a blood rune.11

Events

  • The blog changes Dark Demonbane's rune cost from two soul runes and seven fire runes to one soul rune, four chaos runes and seven fire runes.10
  • The blog changes the rune cost of Thrall spells from five blood runes to four soul runes.11

Trivia

  • Thrall does not work on the Colosseum boss, so no prayer points should be spent on that.12
