Wall of Blades

Your weapon sways back and forth in your hand, ready to block incoming blows.
When an enemy makes an attack against you, you
can initiate this counter to make an attack roll
with any melee weapon you are holding. Use the
higher of your AC or your attack roll as your
effective AC against the attack. You cannot use
this maneuver if you are denied your Dex to AC against the attacker. You can decide to use this
ability after you learn the result of the attack.
