Clarity

Clarity is a sword skill for Assassins, using it works just like Easy Kill or Masterful Kill, when an enemy is about to strike you with a physical attack, you activate Clarity, if you do it right, the Arisen will knock the attacking enemy off balance, and then stab then while their vulnerable, then said Arisen will slash outward. Since Sword Assassins don't have dodge, (Assuming you aren't using a shield at least) this would probably be your best way to defend against physical attacks since you take no damage if you activate Clarity properly. You won't do the outward slash if you use clarity on a bigger monster, like a cyclops. Clarity does not defend against grabs.
