Armor of Sea's Retribution (Breastplate)

This armor is decorated with the parts of an undersea monster. While wearing this armor, you have a +1 bonus to AC and gain a swimming speed equal to your walking speed.

The armor has 3 charges, and it regains all expended charges daily at dawn. When a creature within 5 feet of you damages you while you are wearing this armor, you can use your reaction to expend 1 of this armor's charges and deal 2d10 piercing damage to the creature.

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.
