You should write it to the author of Mimic Miniboss mod. I think he is pretty balanced and need no nerfs, as well as his trinkets. After all it's a monster with desire to kill you, so it should be deadly and annoying)

now we need a general nerf to the mimic miniboss and his trinkets, this Motherf*cker doesnt need 3 turns its soooo annoying

Oh, that's great!

The way you described is exactly what I did.

I do want to ask how it's possible to decrease the mimic spawn by a percentage like you did?

I just manually reduced the "room_treasures: .chance 2 .types eldmimic_chest" In the Dungeon's folder notepad found in the mimic's workshop steamfolder to "room_treasures: .chance 1 .types eldmimic_chest".

It was serviceable, and I don't always find the mimic in all the maps that I do this way but I do want to know how this mod works before I download it and if my custom notepad changes will adversely effect the mod change.
