Cannibal Compulsion

4th-level enchantment

Casting Time: 1 action

Range: 30 feet

Components: V, S, M (a drop of ghoul blood)

Duration: Concentration up to 1 minute

Your spell curses another with an unquenchable physical and spiritual hunger for the flesh of its own kind. This compulsion can affect even mindless creatures or undead, though constructs, plants, and amorphous or incorporeal creatures are immune. The target must succeed at a Wisdom saving throw or be compelled to attack the nearest creature of its own type with bite attacks, to the exclusion of all other forms of attack. If it lacks a bite attack, it makes this attack using only its Strength modifier and is considered proficient with the attack. A successful hit does 1 point of damage and if the target is a creature other than an undead, it must succeed on a DC 10 Constitution saving throw or be paralyzed for 1 minute. Additionally, on a successful hit the target must attempt to initiate a grapple as a bonus action. If a victim of this attack is successfully grappled the bite damage increases to 1d4.

At the end of each of its turns, the target can make another Wisdom saving throw. On a success, the spell ends on the target. Regardless, the target is poisoned from the experience until it finishes a short or long rest.
