A wave of hoarfrost bursts from you in a 30-foot cone. Each creature in the area must make a Constitution saving throw. On a failed save, a creature takes 5d8 cold damage and is slowed until the end of its next turn (its speed is halved and it can't take reactions). On a success, it takes half damage and suffers no additional effects.
