Acid, Oxidizeding Agent (Vial)

When you take the Attack action, you can replace one of your attacks with throwing a vial of Acid. Target one creature or object you can see within 20 feet of yourself. The target must succeed on a Dexterity saving throw (DC 8 plus your Dexterity modifier and Proficiency Bonus) or take 2d6 Acid damage.

• Its damage is increased to 2d10 if the target is a Construct made of metal.

• If the target is a nonmagical metal object, the object takes a -1 penalty to the AC it offers (armor) or to its attack rolls (weapon). Armor is destroyed if the penalty reduces its AC to 10, and a weapon is destroyed if its penalty reaches -5. The penalty can be removed by casting the Mending spell on the item.

• If the target is a nonmagical metal object that isn't being worn or carried, a 1-foot Cube of the object is destroyed.
