 ===Retrieving items===
-Items submerged in lava can be retrieved using a similar process to retrieving them from water, with important distinctions: any organic and flammable items that are not fireproof will typically be destroyed from initially falling into the lava, while the [[invocation item]]s and the [[Amulet of Yendor]] are immune. Freezing the lava will turn it to normal solid ground rather than ice, and the Amulet and invocation items will always emerge on the top of the resulting floor squares; any buried organic items that survived being submerged into the lava will instead gradually rot away in the new floor squares unless they out dug out. A hero can also pull items out of the lava by applying a [[bullwhip]] or [[grappling hook]] while [[levitating]] or [[flying]].

 After jumping to the surface of lava, you could remain on the surface indefinitely as long as you didn't move. After the fix, remaining in place will cause you to start sinking again.
 <!-- Prior to the dev source leak, it was not clear what this bug was supposed to refer to. Communication with the [[DevTeam]] implied that this bug is somehow related to checks for lava effects while submerged in lava being performed at the wrong times (for instance, you can remove [[red dragon scale mail]] in lava and not catch fire even if it was your only source of fire resistance).  However, they had forgotten what specifically the bug was describing.  Examination of the commit history, after the leak, reveals that this bug pertained primarily to commit [https://sourceforge.net/p/nethack/NetHack/ci/d302e6252be60cbb63ef4ce7de7dc446ae710e64 | d302e6] and secondarily to follow-up commits [https://sourceforge.net/p/nethack/NetHack/ci/cba99b52c38b212cd81b5f3e37bebfe0a88aaa7c | cba99b] and [https://sourceforge.net/p/nethack/NetHack/ci/7a084228847d76af3af4a4b81eed1cb8534ce65d | 7a0842].  -->

 ==Description==
-Stepping into lava without [[fire resistance]] will result in [[instadeath|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. Sinking into lava is fatal even with [[magical breathing]]; in the latter case, the cause of death is "dissolved in molten lava". Riding a non-flying/levitating steed over lava will instantly kill your steed, destroy your saddle, and then leave you in the lava.

 If you find yourself stuck in lava, you can free yourself by [[teleport]]ing out, [[pray]]ing, or getting [[engulfed]]. You can also freeze the lava with a cold attack (e.g. [[apply]]ing a [[wand of cold]]) and then [[dig]] yourself with a [[pick-axe]] or other similar tool; for this to work reliably, you must freeze all adjacent squares of lava as well, or the lava might pour into your hole.
-It's possible to walk out of lava on foot. It takes d4+3 moves to escape lava, and d4+11 moves to sink below the surface. However, every move that you don't try to escape (because e.g. you were fighting) adds d4 more turns of being stuck. Spending more than one move on anything than escaping may leave you with too little time to save yourself. Note that once you're stuck, gaining [[levitation]] does ''not'' help you escape by itself.  However, zapping a [[wand of opening]] downwards while levitating will free you.  (If you use the wand ''without'' levitation or [[flying]], you will just get stuck again.  Note also that you cannot put [[levitation boots|levitation]] or [[water walking boots]] on while your feet are stuck.)

 [[Jumping]] while in lava will not allow you to leave the square; unless you have flying or levitation, you will start sinking again immediately, resetting both the time to escape and the time to sink.
