Battle Hunger

Target one creature within 30ft of you. The targeted creature must take a wisdom saving throw equal to your spell save DC or be filled with a violent rage and a burning need for battle. If the target fails the saving throw, at the end of its next turn (and each subsequent turn until the spell ends) it takes d8 psychic damage. The spell ends after five rounds, or when the creature deals five or more damage in a single melee attack.
