I found this room for the first time this evening on level 7 of the dungeon. I have a lot of different mods enabled, as well as the DLCs, so I'm not sure of its source. The signs on the wall seem to give contradicting clues so I'm really not sure of how to solve it yet (I've tried a few different things so far and none have worked) I'm not working for a spoiler, but I just want to know if: 1. does guessing a wrong answer (as I've already done) make it impossible to solve? If so, I'll skip this for now. 2. Is this actually working? 3. Which dlc or mod created this room?
A heads up: There are a total of six puzzles, one for each floor from 5-10. The difficulty generally ramps up with the floor they're found on, although there's one or two puzzles that break this mould. If you feel like cheating, all the answers are in the roomDB as comments.
