Lava is a dungeon feature found in places such as the Valkyrie and Monk Quests and the Plane of Fire.

Stepping into lava is dangerous. Falling into lava without fire resistance will result in instant death, while falling into lava with fire resistance gives you a few turns in which you can escape before sinking below the surface and dying. If you find yourself stuck in lava, you can jump out, freeze the lava with a cold attack such as by a wand of cold and then dig yourself out with a digging implement like a pick-axe, teleport out or pray.

To cross lava, use levitation, fireproof water walking boots, or a cold attack to freeze it. Walking (but not levitating) over lava without fire resistance will damage you every turn you do it.
