Well, got through the crystal caves and Seathe himself without a single death.
Spoiler: show
Now I just have:
Sif> drain New Londo> 4Kings
Bed of Chaos (already killed Ceasless)... I was planning on taking the shortcut, but think I may want to go through Izalith for the challenge (like this whole playthrough isn't one big fucking challenge)
Catacombs > Tomb of Giants > Niito
Hydra> All DLC areas
Stray Demon
Gwyn
The fire sage demon in lost izalith might be a challenge depending on how much my magic does to him because of the fire damage, and centipede demon may be an impossibility because I would have to fight him right at the entrance and to my recollection, if you try to fight him there, all he does is stretch armstrong swipe you.
