Frost Fingers

1-level Evocation

Freezing cold blasts from your fingertips in a 15-foot cone. Each creature in that area must make a Constitution saving throw, taking 2d8 cold damage on a failed save, or half as much damage on a successful one.   The cold freezes nonmagical liquids in the area that aren’t being worn or carried.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
