Ok, go back to the butterfly, but make sure you're human. The last staircase before the fight will have a white summon sign on it. Summon that witch, and she'll fuck the butterfly up for ya.

I think that after that, I went to Blight Town, but I took the entrance through the bottom of the Undead Burg, which is through the depths. The depths was pretty easy, so don't worry too much about that part. Blight town is fucking horrrrrible, though.

Alternately, you can get to Blight Town through the Valley of the Drakes if you want to avoid the parts with all the falls and just deal with all the poison. You'd miss a lot of loot, though.
