Mordenkainen's Lost Notebook

Karmic Aura

1-level Abjuration

While this spell is in effect, a creature within the spell’s area that deals damage to you must make a successful Wisdom saving throw or become poisoned for the duration. A successful save indicates that the attacker is unaffected and immune to the spell’s effect. An attacker already suffering the condition when it hits you suffers no additional effect.   A creature can make another Wisdom saving throw at the end of each of its turns to end the effect on itself.
