With a snap of your fingers, an ice spike flies out to a point you choose within range, blossoming with a quiet cracking into a sphere of frost. Each creature in a 20-foot radius must make a Dexterity saving throw.
A target takes 4d8 cold damage on a failed save, or half as much damage on a successful one.
Additionally, the target will be partially frozen based on how far below the DC they rolled. The effects last until the start of their next turn.
The frost spreads around corners and freezes medium or smaller objects in the area that aren’t worn or carried.

On par with DC	No effect
1 to 3 below DC	Target's speed is dropped by 10 feet
4 to 6 below DC	Target's speed is dropped by half and they can't fly
7 to 9 below DC	Target is Restrained by ice
10+ below DC	Target becomes paralyzed by being entombed in ice
