Resurrect Ghost is a spell within the Arceuus spellbook that requires level 38 Magic to be cast, in addition to having two prayer points. The spell was available to test during the Arceuus Spellbook Beta.
The spell will summon a ghostly thrall, which has an attack speed of 4 (attacking every 2.4 seconds) and attacks using Magic (with a max hit of 1), 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.
Ghostly thralls will remain for a set amount of time ( seconds), but players can cast resurrection spells again after 30 seconds, albeit the existing thrall will disappear if players do so.
After feedback from the beta, the spell was polled in Phosani's Nightmare Poll to have three tiers instead of one, resulting in the release of the spells Resurrect Lesser Ghost, Resurrect Superior Ghost, and Resurrect Greater Ghost.
