Last Stand Chain Shirt Barding

Made of interlocking metal rings, a chain shirt is worn between layers of clothing or leather. This armor offers modest protection to the wearer's upper body and allows the sound of the rings rubbing against one another to be muffled by outer layers.

You have a +1 bonus to AC while wearing this armor, which shimmers softly. If you die while wearing the armor, it is destroyed, and each celestial, fey, and fiend with 30 feet of you must succeed on a DC 15 Charisma saving throw or be banished to its home plane of existence, unless it is already there.

Barding is armor designed to protect an animal's head, neck, chest, and body.

Chain shirt barding provides a mount with an AC of 13.
