I'am really confused on your decisions. like dudeeeee, expaaaanndddd the environment, be creative. It's freaking fantasy dungeon and you just copy pasted your environment.
If he's going to splurge on renovating his dungeon, he should change all the rooms on the 1st couple of floors while he's at it. Since the 3rd is all Forests and the 4th is all Glacial Steppes, maybe make the 1st floor's rooms all Highlands, and the 2nd all Castle Interiors.
