Corrode Metal

2-level Transmutation

Casting Time: 1 action

Range/Area: 60 feet

Components: V, S, M

Materials: a vial of stomach acid

Duration: Concentration, up to 1 minute

Choose a manufactured metal object such as a metal stove, a metal weapon, or a suit of heavy or medium metal armor that you can see within range. You cause the object to begin to rust and corrode. For the duration, the object is vulnerable to bludgeoning, piercing, and slashing damage. The spell has additional effects if the target was a metal weapon, a metal set of armor, or a metal shield.

Armor or Shield. The armor or shield receives a −1 penalty to the AC it offers. Nonmagical armor reduced to an AC of 10 or a nonmagical shield that drops to a +0 bonus is destroyed.
Weapon. The weapon receives a −1 penalty to its attack and damage rolls.

At higher levels: When you cast this spell using a spell slot of 3rd level or higher, and the target is a metal weapon, a metal set of armor, or a metal shield, the penalty increases by −1 for each slot level above 2nd. If a nonmagical weapon’s penalty would be lower than −3, the weapon is destroyed instead.
