Bargina Bitterknuckle's Frigid Fingers

A thin sheet of frost shoots forth from your outstretched fingertips. Each creature in a 20-foot cone must make a Constitution saving throw. On a failed save, a creature takes 3d6 cold damage and is restrained in ice until the end of their next turn. On a successful save, a creature takes half damage and is not restrained.

The frost freezes nonmagical liquids and objects in the area that aren't being worn or carried. Creatures immersed or submerged in non-magical liquid have disadvantage on their saving throws.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the cone's size increases by 10ft for each slot level above 2nd.
