I've tried Thordan and I can get pretty far, but then I just insta die without taking any damage. I just tried S1T7 and got smacked for 390k damage. I kinda doubt Bismark can be done solo, but maybe? I haven't tried. I'm a DK with 490 gear and I'm positive these can be soloed, but I'm just having no luck. Sure, I could throw a party finder together, probably, and get it done, but I'd rather solo them instead if possible.
