You touch a willing creature. Until the spell ends, the targets skin hardens and takes on the color and texture of rough bronze. The target’s AC can’t be less than 15, regardless of what kind of armor it is wearing. While under the effects of this spell, a creature may use a reaction to dismiss this spell to negate a single critical hit or sneak attack from a weapon attack and treat it is as a normal hit. A creature must be conscious and aware of the attack to do so.
