Plane of Fire

From Wikihack

The Plane of Fire is the third of the Elemental Planes. The level is full of lava, fire elementals, salamanders, pit fiends, fire and steam vortices, fire traps, and even a guaranteed red dragon (the only dragon in the game specifically generated with a color).

[edit] Strategy

Upon arrival in the Plane of Fire, you may be banged up from air elementals in the Plane of Air. You may wish to allow a fire vortex to engulf you; not even the Wizard of Yendor can harm you while you are engulfed.

The Plane of Fire is liberally salted with fire traps; thus a cursed scroll of gold detection will not easily find the magic portal. You will probably want to use confused gold detection to distinguish the portal from the fire traps. A side effect to the numerous fire traps is that, since most of the monsters on the Plane of Fire are immune to fire, you will practically be swarmed with a mind-numbing myraid of messages about how "foo stepped in a fire trap but is unharmed", potentially causing you to skip past messages that are A Bad Idea to skip.

Be careful not to get stuck in the lava! Continued levitation is advisable.
