Antigone's Flash Freeze

Cold energy washes over a creature of your choice that you can see within range, freezing the moisture in the air around it.

The target must make a Constitution saving throw. The target takes 8d6 cold damage on a failed save and is restrained until the spell ends or half as much damage on a successful save and it is not restrained and the spell ends.  

A creature restrained by the ice can use its action to make a Strength check against your spell save DC. On a success, it frees itself and the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher,  you target an additional creature above 4th level.
