An abyssal breastplate is made of black iron. It always feels cool to the touch, no matter the temperature. Chaotic energy swirls around the breastplate while someone is attuned to it.

While you are attuned to this breastplate, you have immunity to poison damage. You also have resistance to fire, cold, and lightning damage. Additionally, you can cast hold monster on a demon with a DC of 20. You cannot use this property again until the next dawn.

This breastplate has 5 charges. It regains 1d4+1 charges daily at dawn. You can expend a charge as an action to release chaotic energy in a 20 ft. radius sphere centered on you. Each creature in that area must succeed on a DC 18 Wisdom save or take 22 (5d8) psychic damage and be frightened for one minute. On a success a creature takes half the damage and is not frightened. A frightened creature can repeat the saving throw at the end of its turns, ending the condition on a success.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.

Notes: Immunity: Poison, Resistance: Cold, Resistance: Fire, Resistance: Lightning, creature with a chaotic evil alignment
