Icicle Strike

1-level Evocation

You launch thin, petal-like shards of ice forming a unwavering barrage in a line 30 feet long and 5 feet wide racing out from you in a direction you choose. Each creature in the line must make a Constitution saving throw. A creature takes 2d6 cold damage on a failed save, or half as much damage on a successful one.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
