Bloodlust Cloud
3rd-level enchantment
Casting Time: 1 action
Range: 120 feet
Components: V, S, M (a tiny vial of blood)
Duration: Concentration, up to 1 minute
At your command, a cloud of red vapors rises in a 20-foot-radius sphere, spreading around corners. The area within the cloud is heavily obscured, reducing darkvision beyond 5 feet. The cloud can be dispersed by a moderate wind.
Any creature that is below half its maximum hit points and ends its turn inside the Bloodlust Cloud must make a Wisdom saving throw. On a failure, the creature is compelled to make a melee attack against a random adjacent creature on its next turn.
