Btw, have you guys tried returning to the prologue level?
I got skull fucked by the boss, but I killed the two black knights and that dude that gave me the Estus Flask at the beginning. Got all the items there as well, including the ring that lets you run freely in the swamps and shit. Should come in handy when I go back to Blighttown. Also left a dung pie in that nest, quit the game, reloaded and it had turned into something good that I'm forgetting now.
