Therefore, you are leaving yourself opened to a frontal attack if you failed to execute this maneuver. Note: This technique will be difficult to perform due to the parry timing and that you cannot parry while blocking. During the riposte animation, you will be invulnerable to other enemy attacks. Immediately press the RB/R1 button to counter the attack by performing a riposte. If timed correctly, your character will swat the enemy's weapon away and cause the enemy to stagger. The first step involves you parrying with your shield (you can parry with most shields) by pressing the LT/L2 button right before an enemy lands their attack. A two-step technique that will cause more critical attack damage than a backstab.
