Maybe I just haven't played in a while and don't remember anything but I don't think I had too many problems in the Zisteau Cavern.. it was pretty straight forward. The spot around the button in eternal battle was pretty calm (tbh) looking at the rest of the area. I don't remember getting swarmed there (well, just the potions )
I dont know about you guys, I just saw that the button is wooden (wow!) so I just shot it and got out pretty quickly (hell even survived the lava somehow with the sliver of health lmao)
Of course Inferno Mines is flawed map (hell there's hardly anything good about it) but no need to call the stuff you failed to understand 'bad' though. That's why everyone leaves tons of signs and books now, people just don't believe that someone will figure out their mechanic on their own lol.
