It's guessin' time i guess
Self explanatory.
I’ve been there. I would start from the end in case some are from lvl1. Maybe use the id scroll. Or just keep going down until you ID a few if you really want to not waste.
Yea, I started by the end. Wasted a mind vision and another one I don't really remember. Either way, I later died.
Tragic. That mind vision potion was totally going to save you.
At least you're near water and a door to get rid of fire and poison gas.
