3 non-sapient creatures within 1,000 feet and eyeshot must make a DC 17 Intelligence check. Upon failure, they become ravenously carnivorous, attacking any living creature in sight of a different species, or of the same species if that species is so inclined. The creature will spend a turn after a kill feasting upon the corpse, then return to killing if there are other creatures around. Creatures trained for loyalty must beat a DC 7 Intelligence check.
If this spell is performed as a 6-hour long ritual, every non-sapient creature within 1,000 feet must make the save, and suffer the effects if they fail.
If the creature sees another creature with whom it has a deep bond, it will make a DC 13 Charisma save to snap out of its violent spell and return to its senses. Otherwise, it will still attack them.
