Chilling Gaze

Your eyes become imbued with terrifying, icy energy. You look at a creature within range that can see you, and you force it to make a Wisdom saving throw. On a successful save, the creature takes 3d10 cold damage, and the spell ends. On a failed save, the creature takes 3d10 cold damage, and turns into magical frost. While in this form, it is paralyzed. While paralyzed in this way, the creature has vulnerability to fire and bludgeoning damage, but is immune to cold damage. The creature also takes 1d10 cold damage at the start of each of its turns, which ignore its immunity. The creature can repeat the saving throw at the start of each of its turns, ending the effect on it on a success.
