Cold Snap

A sphere of cold encases an you see within range and then implodes. The caster must be able to clearly see the targeted area. For example, if they were trapped inside of a clear glass cube, they can cast the spell at targets who are outside of the cube.

Each creature in a 20-foot-radius sphere centred on that point must make a Constitution saving throw. A target takes 9d4 cold damage on a failed save, or half as much damage on a successful one.

The cold envelops the affected area and is covered in a layer of frost.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level above 3rd.
