Well, despite the purging and [/spoiler]bans that I really don't even know why I deserved, my quest continues. I cleared Act 3, almost died at Mephisto when I thought I had cleared all of his goons but there was a little herd tucked behind him and they all rushed me at once when I approached him. I must have had like 20 HP left but I survived. I got a little cocky because he's always the easiest act boss aside from andy, but he was a bit more threatening this time with my limited tools.
I'm well into A4 now and I've managed to gear up a tiny bit, my damage sucks ass (49-118) but I have a bunch of magic find gear and pretty good defense. Concentration has helped a lot. I was smart and decided to grind for Ral runes to put in a 3os kite shield, and the fire resistance has saved me several times. I only have 2 Rals in it but I'm gonna look for a third before I hit Diablo, and hopefully get some lightning resist as well. I've had more luck than I deserve so far, I probably should have been dead about 10 times by now but with any luck, maybe I'll save Sanctuary.
