Requirement: You must be wielding a light blade.

Effect: Choose one creature adjacent to you. Until the stance ends, whenever the chosen creature is adjacent to you and takes damage from a melee or a ranged attack while you are wielding a light blade, you can make a melee basic attack against it as an opportunity action. In addition, your basic attacks against the target gain the rattling keyword.
