Bracers of the Bloodied Beast (5e Equipment)

Wondrous Item, rare (requires attunement by a Lycanthrope)

While you are attuned to these bracelets you gain a +1 to AC.

Additionally, whenever you use the Attack action and make an attack with an Unarmed Attack or Natural Weapon, you can make an additional attack as a bonus action using the same weapon. If you dealt damage to the target this turn, the extra attack had advantage.

Curse: The first time each round you attack a creature, you have disadvantage on attack rolls against other creatures until the start of your next turn.
