Unravelling Revelation

You batter the minds of creatures in range with multiple visions of their own doom. Each creature in a 20-foot-radius sphere centered on that point must make a Wisdom saving throw. A target takes 6d6 Psychic damage on a failed save and be Incapacitated until the end of their next turn, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
