Cryokinesis

Effect

As an Action, you rapidly draw heat out of the environment, freezing air, ground, or surfaces. Choose either a 15 ft cone originating from you or a 10 ft radius patch of ground within 30 ft that you can see. Each creature in the area must make a Dexterity saving throw (DC = 8 + your Proficiency Bonus + your Wisdom modifier). On a failed save, the creature takes 2d6 cold damage and its movement speed becomes 0 until the start of its next turn. On a successful save, the creature takes half damage and its movement speed is halved until the start of its next turn. The frozen ground in the affected area counts as difficult terrain until the start of your next turn.
