Stellular Strike

4-level Transmutation

You conjure down a 10-foot radius, 40-foot high cylinder of blinding astral light at a point that you can see within range. Each creature caught in the light must succeed on a Constitution saving throw or be petrified in hardened stardust until the start of your next turn.
At higher levels: When you cast this spell using a 5th-level spell slot or higher, the radius increases by 5 feet per spell slot level expended above 4th.
