You awaken an unnatural hunger in the target, compelling them to fall upon a nearby helpless or dead humanoid creature and begin eating its flesh. Your target defends itself normally but takes no other actions while eating. The target does not take extraordinary risks to satisfy this urge (it wouldn't jump over a pit or swim through lava to reach a suitable victim). If the subject can’t fulfill this urge on its next turn, the spell fails. Each round on its turn, the subject gets a new Saving Throw to end the effect.

Note: This spell also appeared as a second level spell on the Blackguard spell list. As that class does not exist in Pathfinder it has been removed.
