Breadskin

You touch a willing creature, causing a layer of spongy bread to grow from its skin, quickly forming a hard, golden outer crust which lasts for the spell’s duration. Until the spell ends, the target reduces each instance of bludgeoning, piercing, or slashing damage it takes from nonmagical attacks by 2. The spell ends early if the target is ever submerged in water or has 5 or more gallons of water poured on it.

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