As an action, you can use Stealth without using an action. Additionally, before the end of your next turn, you can add the stamina die to an attack’s damage (add half on a miss by 4 or less) if you have advantage on the attack, or if the creature is within 1 meter of an enemy of the creature that isn’t incapacitated and you don’t have disadvantage on the attack.

Enhance

You can increase the damage for each additional stamina die expended.
