Celestial Crusher

The user conjures two, large masses of celestial energy to crush enemies in a 25 foot cube. All creatures in this cube must succeed on a strength saving throw or take 6d10 radiant damage and become stunned until the end of your next turn. Creatures that save take half damage and do not become stunned.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d10 for each level above 5th.
