Reanimate Giant is a reanimation spell in the Arceuus spellbook. It requires an Ensouled giant head to cast and will summon a Reanimated giant with 35 hitpoints. Killing this creature will give 650 Prayer experience and 0.5% favour towards the Arceuus House.

A Magic level of 37 is required to cast this spell and it rewards 74 experience. It requires 1 Soul rune, 2 Nature runes, and 4 Body runes to cast.

As with all reanimation spells, this spell may be cast anywhere in Gielinor ONLY if the ensouled head was obtained as a drop from the monster directly and then used in within an appropriate timeframe in the area where the monster was killed.

If you do not cast the spell shortly after receiving the ensouled head as the drop, then the reanimation spell must be cast within range of the Dark Altar. The spell must be cast at the Dark Altar if any of the following conditions are met:

• The ensouled head is obtained from other players.
• You teleported away from the area after receiving the ensouled head as a drop.
• You wait too long before casting the reanimation spell within the area where the ensouled head was dropped.
