Parry Mechanic (for combat)

When battling, you can press a certain key (possibly the attack button) when someone hits you, allowing you to parry it. This could be better as a shield because it could activate a special attack, and do barely any durability. Depending on what item you have equipped, it will do something different. Swords could do a very wider sweep, an axe could do a short throw, a spear could do a lunge, a mace could do a jump in the air, etc.
