Thrall

Thralls are undead beings which can be summoned to attack enemies.

Overview

Thralls are summoned with resurrection spells in the Arceuus spellbook, which requires completion of A Kingdom Divided. In addition to the required Magic level and runes, the player must have the book of the dead either wielded or in their inventory, along with 2-6 prayer points in order to summon a thrall.

Thralls are very powerful allies as while they hit very low (their max hit being 1 to 3 depending on tier), they are almost always guaranteed to hit and ignore the target's defensive bonuses (zeroes are possible), which is especially useful for combat achievements requiring speed kills and places where magic spells (not including powered staves) are not needed. Thralls have an attack speed of 4, or once every 2.4 seconds.

The magic thralls' projectiles will hit enemies 1 tick earlier than the ranged thralls. Therefore, magic thralls are preferred whenever there are no special type resistances.

Thralls will remain for a set amount of time ($0.6*CurrentMagicLevel$ seconds). There is a ten second cooldown before the player can cast another resurrection spell, although the current thrall will despawn in the process.

As the thrall's duration is dependent on the player's Magic level, boosting it will subsequently increase the thrall's duration:

Required for Resurrect Lesser spells

Required for Resurrect Superior spells

Required for Resurrect Greater spells

Maximum magic level

Maximum magic level with imbued heart boost

Maximum magic level with saturated heart boost

Maximum magic level with Overload (+) in Chambers of Xeric

Maximum magic level with Smelling salts in Tombs of Amascut

Thralls cannot pass between rooms (for example, a thrall summoned in the Corporeal Beast lobby will remain there even when the player enters the Beast's arena and attacks it)
