More solo exploration with a defender.
Freaks saw through my good invisibility. Two groups did; other Freaks did not.
I approached a gladiator with a full inspiration rack (not wise). Gladiator attempted to give me one. There's a timing problem here - I think I should have to click on any gladiator that isn't automatically hostile in order to get a response. Another I met just gave advice.
Orange - yes, completely random groups. Totally unnatural.
Found another malevolent fog. It seemed to take damage faster than yesterday. Maybe I was level shifted more (+4). Do these things have a level, rather than using Giant Monster code? Unfortunately, the minotaur showed up and ended that attempt.
I set a thumbtack in a particularly confusing room. Then I died. From the lobby, I had waypoints through the red portal and two other doors that, sure enough, brought me back to the thumbtacked zone.
Popped an inspiration in the colonnade and was disappointed at how little time that showed me the path (15 seconds?). Mapped my way through it afterwards, and I see I am not the first.
