For me I think that the dungeons, monster, and quests was fairly easy, except for blinky. You could farm the tokens very fast, and you could get the heroblade without much trouble, but some people just use bots now. I've never tried the grimblight before so i don't know about that, but i think it's a little too overpriced. Freakin' thing costs the same as buying a class. Might as well spend ac's on classes.
