FRIGID BLAST3rd-level evocation (Wizard)
Casting Time: 1 action
Range: 150 feet
Components: V, S, M (a pinch of powdered crystal)
A bluish streak flashes from your pointing finger to a point you choose within range and then explodes in a blast of frigid ice and cold. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 cold damage on a failed save, or half as much damage on a successful one.
The frigid cold and ice spreads around corners and damages objects that aren't being worn or carried.
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.
