Dungeon branches
The page provides a map of the various dungeon branches and how they interconnect. For tips and tricks on surviving the individual branches, see the walkthrough and the branches' individual pages.

Miscellaneous Portals
Optional portals to fantastic extra-dimensional realms can be randomly found throughout the Dungeon and its branches. While none of these contain runes, they nearly always contain above-average loot and useful experience. If you know how to handle each one's theme, they can often be cleared without excessive risk. All such portals are single-entry only, and after you exit their realm, they will be gone along with anything you left inside.
Unless otherwise noted, all these portals are temporary, and will disappear if not entered within a certain length of time. There are actually two clocks running: a shorter countdown while you're on the level with the portal, and a longer one when you've gone to another level. If you stay on the level, you'll receive increasingly urgent messages as the timer runs out, and the portal's appearance (check with 'x', then 'v') may indicate how much of the timer has expired. When a portal on your current level expires, you will get a message to the effect of, "The walls and floor of the dungeon suddenly vibrate!" Portals will not start closing until you reach the floor that they are on, so there's no need to rush through early floors in order to access them.
Bailey - A keep guarded by gnolls, goblins, and/or orcs.
Bazaar - Shopping spree! A safe area with several shops, make sure you enter with a good amount of gold.
Desolation of Salt - A crumbling wasteland filled with unique constructs and other guardians lurking among its salt clouds.
Ice Cave - Freezing clouds, wild animals, and occasionally icy demons.
Gauntlet - A choice between several arenas. Taking the challenge will get you some loot, but also pits you against a deadly minotaur.
Ossuary - A small tomb filled with mummies and their undead guardians.
The Sewers - Fetid waterways teeming with rats, snakes, and occasionally nastier things.
Treasure trove - Contains several acquirement-level items, but getting in requires giving up a rare and valuable item in return. Is always permanent.
Volcano - Fire and lava everywhere. Also lava-dwelling creatures.
Wizard Laboratory - The abandoned laboratory of one of several famous mages.
Ziggurat - The ultimate challenge: 27 floors of increasingly difficult battles, but with riches untold for those who win through. Ziggurat portals are permanent, but only one spawns naturally in the Depths. They are also created from evoking a figurine of a ziggurat, which can be found on Tomb:3 and on level 27 of a previous ziggurat.
