Bark Wraps of the Fey

Constructed from cloth and the bark of a special tree found only in the feywild, while wearing the wraps you gain a +1 bonus to the attack rolls and the damage rolls you make with unarmed strikes and natural weapons. Such attacks are considered to be magical.

Also the Bark itself has special properties that allow a monk once attuned to store a small reservoir of energy in form of your Ki, the bark can store up to 2 Ki points.

As an action you can spend 1-2 Ki to charge the Bark with energy, 

When you spend Ki it is always spent from the reservoir first.
