Armor of The Heart

You have a +1 bonus to AC while wearing this armor. During combat, when one of your allies within 30 ft. of you is about to be attacked and suffer damage, you can use your reaction to decrease your AC by 2 and increase your allies AC by 2 until the end of your next turn. You can use this ability twice per long rest.

This armor consists of a coat and leggings (and perhaps a separate skirt) of leather covered with overlapping pieces of metal, much like the scales of a fish. The suit includes gauntlets.

Notes: Bonus: Armor Class, Cleric, Paladin or Ranger, Combat, Warding, Stealth Disadvantage
