Yeahhh I usually co-op down in the depths to help people get through it. It's a fun place, and the gaping dragon, although predictable (after the first few times you die learning his move-set) is still a fun long boss battle.

But yeah, the black knight halberd is just intense, on the character I have with it, I can't use it 1-handed but it's pretty damn cool looking in move-set, and it's damage is ridiculous for un-upgraded.

Alright, I beat dukes archives and I FRICKIN' HATE the enemies thereARCHERS BUFFED BY CHANNELERS, CHANNELERS BUFFED BY CHANNELERS, AND GAHHHHHHHHH
But really, after I beat the boss I went back to finish up Logan's sidequestkilling Logan for his stuff, and it took me like 35 minutes of pain and rage to get back to him. I was impatient aafter the dungeon, so I just wanted to kill Logan yet in my rush I kept getting flanked, ganked, and shot constantly, resulting in much frustrating death. In the end though, I got his stuff... though I will probably only occasionally use it (I prefer my current armor set)
I'm trying not to level anymore and just pump all my souls into equipment... but oh man co-op is just so fun I have too many souls I don't know what to do with.
Well, onto The ToTG and New Londo ruins, I know these two areas like the back of my hand from past characters~
