As an action, you can make a melee weapon attack along with a deceptive or pretended blow, thrust, or other movement. Add the stamina die to the attack’s damage (add half if you miss by 4 or less). On a hit, the creature must succeed on an Insight ability check or you have advantage on your next melee weapon attack roll against that creature before the end of your next turn.
You can increase the damage for each additional stamina die expended.
You can expend 3 additional stamina dice to have advantage on all attack rolls against the creature if the attack is made before the start of your next turn.
