Went to Phosphor, Got Jump-Scared!

I didn't know lanterns were recommended, so I charged in with just goggles and almost died. So that's why they had lantern buffs... "The map design is amazing!" ...I was so busy looking up at things like workbenches that I kept getting caught by the spike traps (?) and bear traps. Next thing I knew, enemies were behind me, I was suddenly trapped in darkness, or hands would pop out. I was on edge the whole time, but I've gotten used to it enough to tackle Nightmare co-op. Phosphor has a large map and the objective ink marks are often high up, so maybe it's recommended for co-op...? From now on, it'll probably be like: Speed runs -> Manor, Ink mark farming -> Phosphor. By the way, I got a sapphire. Other players seemed to get the Pumpkin Lord with pretty high probability. No one had gotten the Mutula's Core. I'll try diving in again on the weekend to aim for the Mutula's Core.
