Understandable on the limitations. DD is kind of a quirky frame to work with; Recently learned of using the upgrade discount buff stat type for making custom descriptions, which is pretty funny.

Many fights reward nothing, making the minor artifact from anti the only drop usually. Is that to balance out the gold you get from curios? why make parts of the dungeon one way?

Dark diamonds being 13,500 gold for a stack makes them the highest gold/inventory slot in the game. Being nearly twice that of major artifacts, better than a full 20 stack of minor artifacts by 3,500. I left that 88k gold run with 4 open inventory slots.
I think it would be a good idea if you want to maintain the extreme gold potential of the cemetery to make it harder to carry that much out, making inventory management needed to achieve that potential. As is I might fork the mod, edit the values for my own use. Not distributing it of course, but just for my own personal run since gold is a non-factor with how easy it is to earn in the cemetery.

I understand the nightmare creature type, and its implementation; Why the zombie type instead of just unholy?

Is it intentional that the Terror's apperate attack doesn't trigger riposte?
