Chrono Flare

You detonate a burst of unstable temporal energy. Each creature in a 30-foot-radius sphere centered on a point you choose within range must make a Wisdom saving throw. A creature takes 10d6 radiant damage + 10d6 psychic damage on a failed save, or half as much on a successful one.

On a failed save, the creature is also blinded and stunned until the end of your next turn, as their perception of time fractures violently.
