Quori Embodiment

The connection between your material body and the spirits it houses becomes more actualize. You gain +1 to Wisdom. Additionally, when you make a melee attack, you may sacrifice a hit die to add 1D8 to the attack roll. You may choose to do this after you have made an attack roll but before you know the result. You may use this ability a number of times equal to your proficiency modifier per long rest, so long as you have hit dice to sacrifice.
