With any luck, this challenge won't survive the exploits getting fixed and balance changes (unless they remove the level restriction on One Many Army, in which case it should). I did only exploit fleeing for the final battle, though. The rest of the game I didn't exploit anything except Enrage + Crippling Blow. So, it's still pretty easy.
I'm doing another run as a memory mage, but this time I'm not exploiting anything but CC (no fleeing). It's easier than the Enrage Knight was so far, but I guess I'll have to see about the final fight.
But, yeah, without doing a One Many Army challenge, I'd have never realized how broken Fleeing was, because with a full party I never once felt like I needed it.
