Madness of the Moon

7th-level enchantment

Casting Time: 1 action

Range: 60 feet

Components: V, S, M (a fragment of a cracked mirror)

Duration: Concentration, up to 1 minute

You channel the chaotic influence of the moon to send up to three creatures within range into a frenzy of madness. Each target must make a Wisdom saving throw. On a failed save, a creature takes 8d8 psychic damage and suffers from short-term madness for the duration. On a successful save, it takes half as much damage and is not affected by madness. The creature can repeat the saving throw at the end of each of its turns, ending the madness on a success.
