Scorned Heart Breastplate

Alter: This brass breastplate is torn apart in its center by a crimson gemstone. You gain a +1 bonus to AC for every 2 allies within 10 feet of you (max +2 AC) while you wear the armor. In addition, while wearing the armor, you can cast hellish rebuke (save DC 15) as a 3rd level spell from it, using your reaction. Once this spell has been cast by the armor, it cannot cast it again until the next dawn.

Attunement: Yes, cursed
Curse: This armor is cursed. Attuning to the armor extends the curse to you until you are the target of remove curse or similar magic; removing the armor fails to end the curse. While cursed, you have disadvantage on saving throws to resist being charmed, and you have disadvantage on Charisma checks to interact with any creature you find attractive.
