Not as strong as most bladed weapons, the parrying blade has trouble against larger, heavier blades. Still, it is quite impressive to see a skilled swordsman using a quick blade in one hand and a parrying blade in the other.
You may use Parrying Blade if you are using another one-handed Weapon of Choice. Your opponent's first attack during his turn cannot be to an area that your last defense played blocked during your turn. If you make a Power Block, you must discard the top 3 cards from your Endurance. You can only have one Parrying Blade in play.
