Exp/lvl cap?

I’m fairly sure I read a post a while ago, mentioning that as far as experience/monster killed, the monsters stop giving more exp at a certain lvl. Just can’t find the post, and can’t remember if it was a matter of difficulty AND map lvl, or just one of them. Anyone who can help?

It’s above floor 100 but increasing difficulties does increase the amount of XP you get! :smile:
