every successful parry will hold 250% of damage taken and you can choose to launch it back as either visible noise (earrape) or an unrelenting force (fus-ro-dah) that flings the enemy. if you get hit & miss a parry, you kinda just have the same effects as the amulet of conservation but buffed to 150%, and removing the coil will result in all accumulated and uncountered damage being inflicted on the user all at once.
