Cold Embrace

With this spell, you can shield a willing creature within range in ice until the end of your next turn.  While encased in ice, the creature has immunity to bludgeoning, piercing, and slashing damage and regains 2d6 hit points at the beginning of its turn.  The creature is incapacitated for the duration.

At Higher Levels.  When you case this spell using a spell slot of 3rd level or higher, the duration of the spell increases by 1 round for each slot level above 2nd.
