Bursting Icicle

An icicle appears above a space you can see within range. It falls and, immediately before impact, explodes in a cone of ice fragments. Any creature in the space must succeed on a Dexterity Saving Throw or take 2d4 Cold damage.

The spell's damage increases by two die when you reach 5th level (4d4), 11th level (6d4), and 17th level (8d4).
