Avalanche

You create falling of ice and snow that cascades from your location. Each creature within a 5-foot radius, other than you, must succeed on a Strength saving throw or take 1d6 cold damage.

While concentrating on this cantrip, you may spend your bonus action at the start of your turn to extend the radius of the falling ice and snow from 5-feet to 10-feet, but lowering the damage of all die to d4 instead of d6. If you do not spend your bonus action the following round after extending the radius, the radius returns to 5-feet. The ice and snow disappear when the spell ends.

At Higher Levels: The damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
