Okay, the fire tower was complete trash. Some dudes wandering around in the lava heard me floors below and then wouldn't let me get past them without outing my position. Maybe I could've used the gas arrows for that part (???), but I didn't want to accidentally get environmental kills either. Ah well, I made off like a bandit with only 450 coins worth of stuff missed.
Onto the Lost City now. Sounds like a zombie hangout, so I brought flashbangs.

Take me down from the ridge where the summer ends
And watch the city spread out just like a jet's flame
