Built from enormous blocks of obsidian, the volcano's sweltering chambers may once have served as a temple to some strange deity, or perhaps the dwelling of a mighty fire giant. The air shimmers with oppressive heat, and the dull roar of the volcano's heart never ceases.
Leading directly into the rock is a dark and forbidding tunnel. Every so often air, hot enough to singe your face, blasts from within, and, as though triggered by the air, rocks fall from the roof and sides of the tunnel, slowly filling the entry.

Volcano portal.pngThe Volcano is a single-floor mini-branch one can reach via a timed portal that shows up in the early- to mid-game; the Lair or the Orcish Mines are common location for such entrances. The Volcano usually contains fire-themed monsters and loot, but may also feature the undead, various humanoids (armed with fire-branded equipment)and a surprising number of toenail golems. Its most defining feature is that it occasionally erupts, with predictably dreadful results.


Although some variation is possible, the volcano generally consists of a small entrance area, a large central chamber with a lava pool taking up much of the area, in the center of which is a stone- or metal-walled chamber filled with fire-themed loot and powerful monsters. Other formats can incorporate twisting, narrow passages or a small central chamber with multiple branches each containing small piles of loot. One possible layout is a stone structure that is completely shielded from the volcano; eruptions here will instead collapse portions of the roof, sealing off the treasure chambers one by one. Move quickly if you want to get the treasure.

Be aware of the message, "The air gets thick with the scent of sulphur." This means that large portions of the volcano will soon be filling with fire clouds, and in some maps will cause new rock walls to form. If this happens, you may need a source of flight and a wand of digging to fully explore certain maps.


  • Even a single rank of fire resistance can make a big difference. Pile it on as best you can. If you lack it, be aware that much of the loot found here will provide it, including items that normally never offer the fire resistance ego. You'll face a brutal fight on your way through to get it, however; don't be afraid to quaff a potion of resistance or two to help you survive the heaviest fighting.
  • If you have Mephitic Cloud, you can avoid eruptions easily by creating mephitic clouds on yourself before the eruption occurs. New clouds cannot form on tiles that already have existing clouds. Just don't wander around while confused.
  • Most things found here will be weak against cold.
  • Stealth helps tremendously here, giving you the option of ignoring all those pesky monsters living in the lava which really don't pay off when killed.
