Chilly Feet

As you hold your hands facing the ground with open palms and fingers spread, a strong gust of cold, icy wind erupts from your body. Each creature in a 15 foot radius of you must make a constitution saving throw. A creature has it's movement reduced to Zero on a failed save, or by 10 feet on a successful one, as their movement base limbs (Wings, feet, fins etc.) start to freeze over. Any creature affected by this spell can’t benefit from any bonus to its speed and has disadvantage on dexterity saving throws.

Effects of this spell last for half a minute. A creature affected by the ice can use its action to make a Strength check against your spell save DC. On a success, it frees itself.
