General
The exit portal that takes you to the Gatekeepers is very heavily guarded by wisps, ghosts, and mu-miyahs. The mu-miyahs in particular hit very hard. There is a door right before the exit portal that is usually blocked by a wisp. It makes it a lot easier to open the door if you can war or missle the wisp in front of the door from a distance before running up. Get through the portal as fast as possible.
This is one of the few places where fixed location Sturdy Steel Chests can be found.
