Dark Souls - Blighttown, oh god Blighttown. After spending nearly my entire day getting summoned for Gaping Dragon runs, I ended up attempting this sucker of a place. I had 5 Rings of Sacrifice I bought just for this place until I could reach a bonfire, arming myself with a new one everytime I died.
...I had one left when I reached one about halfway down. Most of the time I just fell to my doom basically xD.
Next bonfire I reached wasn't quite as bad to reach, but still...damn near everything and their offspring being able to induce poison was evil. So were the dart throwers who could induce toxin in like 2-3 hits max.
As for the boss, it was honestly the easiest thing about this stage, even if I did have two extra people with me because I thought those mini leeches inside Quelaag's Domain were gonna cause me hell (Yeah I died to them, go me). Turns out I wasn't supposed to kill the enemies with giant ass growths on their backs cause that's where the mini leeches came from. Oops.
Anyways, the boss didn't really have anything going for it that was super overly dangerous. The lava vomit attack was easily dodged, then the strategy was to basically stay as close to her as possible. The only attack everyone had to back off here for was the one where she rears up and hits the ground hard. AoE attack essentially. Even then, the one time I got hit by it didn't utterly wreck my HP bar, maybe 1/3rd of it, if that. Easily remedied with a quickie Estus Flask.
Second bell rung, new area opened up. Still have like one area to go explore in Blighttown. Fan-freaking-tastic D:.
