Shatterer of Nails/Infected

In this variant, Shatterer of Nails is similar to his normal variant, but he is hunched over and has Infection bulbs sprouting out of him in various places. He is fought in the Abyss after all other bosses, save the Nail Father, have been fought. When staggered, a single hit won't end the phase. Instead, Red should slash at one of his Infection bulbs. He should have enough time to destroy it before the Shatterer of Nails gets back up.
