Common Only Run

Thinking about how common items have only ever served as a handful of extra emeralds at the blacksmith whenever I play; how challenging would this actually be compared to some of the officially supported challenge modes? I am not that in-tune with the pro meta , I have never reach level 70.

 

Pretty difficult. I've tried a similar run before (that I still need to finish) and found that it starts getting a bit painful around the 40s, and then gets drastically worse the higher you go. The main issue is that lategame, you have weapons that deal the damage that a decent level 70ish weapon deals but with no identifications. This means 0 mana sustain, 0 ability to tierstack, 0 ability to heavy melee, and 0 walk speed bonus. You'd be relying on your skill tree for basically everything. It's definitely better than something like a 0 crafting craftsman but still pretty painful.
