just some thoughts

I can't really say that I'm that good of a tome player so take what I say with a grain of salt. I've been doing runs of stone warden in the infinite dungeon and have yet to reach that far down but what I see makes me a tiny bit angry. namely at least with shopping with infinite 500. so I come here to kind rant and also to look at how that mod along with others could be changed. the shops both in the dungeon and other wise seem to never give you what an item is truly worth. again just my thoughts, still can we get better prices? and why is it that normal monster levels on level 1 of the infinite dungeon are sometimes so high? level 1 against lvl 7

Out of Depth monsters can be

Out of Depth monsters can be a real pain, especially the named ones, try browsing the addons if you havent already their may be one that tweaks either the shopkeepers or the dungeons to your liking, if not try suggesting in the forums. If all else fails Lua isnt to hard to learn It might be a chance to play with some of the code your self and make an Addon. see the wiki for further details.

Roguelikeness

I dont think i ever thought of it that way,the out of depth .. 1 hit KO seems in line with roguelikes but you do have a point.Maybe the first 5 floors could have regular scaling with 1 T1 or T2 boss or something then scale normally?
