An ensouled imp head is an item which can be dropped by imps. It is used to gain Prayer experience by using the level 12 Magic spell Reanimate Imp from the Arceuus spellbook, granting 24 Magic experience.
The head can be reanimated anywhere across Gielinor only if the spell is cast on the head while it is still on the ground. Once the head has been picked up, it must be taken to the Dark Altar in Arceuus to be reanimated.
Killing a reanimated imp gives 286 Prayer experience.
