Well, the overall rule is that if there is a boss that you can't take solo then don't. Medusa is one such that tends to cause problems. Razor Lurker is always a pain. Number 81 (second boss in DOD) used to be another for me.
Sure, there might be a way you can get lucky and either not get stoned or break it. But, it is not like HOTO is a must-have run these days. Besides aggs, there is nothing there anymore. People still wear HOS, and of course, ZS/DL gear. Hoto is meh.

Oh, and people who have more than 3 classes are clinically insane.
