OK, got through the first part of the triple quest. I think I can do it pretty consistently now that I've figured out how it works, but the monster difficulty is obnoxiously high...
Also, never prepping Draining Blade for a triple quest again.

Part 2 looks pretty difficult. I was instantly trapped behind high level enemies, and even the Tinker's two walls didn't help me get anywhere. Seems like getting a positioning glyph of some kind from part 1 is a good idea, but those aren't guaranteed to spawn... also, probably it's good to keep LEMMISI if you get some conversion fodder in shops to make up for the hit against the boss. I screwed up and had to use reflexes on a level 10 goat, but reflexes is probably best used on the first boss, instead.
