Barrier Bracer

This item has 10 charges and regains 1d6 + 4 expended charges daily at dawn.

Hexpansive Defence. While wearing this bracer, when you or a creature you can see within 5 feet of you are hit by an attack, you can use your reaction to expend up to 5 charges, causing its shield to grow progressively larger with each one. The target of the attack gains a +1 bonus to AC against the triggering attack for each charge spent.

Hextech Recharge. As an action, you can slot a gemstone worth 50 gp or more into the item, which immediately destroys the gemstone and regains 1 charge. Once this property of the item has been used, it can’t be used again until the next dawn.
