Resurrect Greater Skeleton is a spell within the Arceuus spellbook that requires level 76 Magic and the completion of A Kingdom Divided to be cast. In addition to the required runes, casting this spell requires six prayer points and having the book of the dead equipped or in the player's inventory.
The spell will summon a greater skeletal thrall, which has an attack speed of 4 (attacking every 2.4 seconds) and attacks using Ranged (with a max hit of 3), ignoring any accuracy checks in the process. They will attack the same target that the player is attacking, and cannot be damaged. However, they cannot attack other players. Damage dealt by the thrall counts as damage dealt by the player that summoned it.
Thralls will remain for a set amount of time ( seconds), but players can cast resurrection spells again after 10 seconds, albeit the existing thrall will disappear if players do so.
