Darastrix's Icicle Storm

A hail of pointed icicles falls to the ground in a 20- foot-radius, 40-foot-high cylinder centered on a point within range. Each creature in the cylinder must make a Dexterity saving throw. A creature takes 2d6 piercing damage and 4d8 cold damage on a failed save, or half as much damage on a successful one.

Creatures that fail the saving throw are also restrained by the chilling ice until the start of their next turn.

Icicles turn the storm's area of effect into difficult terrain until the end of your next turn.
