In [[EvilHack]], '''[[Gehennom]]''' has been significantly revamped from its layout and composition in vanilla ''[[NetHack]]''. The depths of Gehennom are filled with hellish-caverns and rivers of [[lava]], and [[fire resistance]] is required to avoid being burned alive: a [[hero]] that does not have [[Partial intrinsic|full fire resistance]] will take fire damage each turn ('''"The flames of hell are <slowly> roasting you alive!"'''), with the damage proportionate to the amount of fire resistance the hero has.

Gehennom guarantees that heroes will encounter four different [[demon lords and princes]] within more elaborate lairs, and the demon rulers themselves are more deadly than in most variants—while the demon and devil rulers are not invincible, the average hero will require far more strategy and higher-quality equipment in order to reliably best them and advance to [[Wizard's Tower (EvilHack)|The Wizard's Tower]].

==Generation==
As in ''NetHack'', Gehennom is situated beneath [[Castle (dNetHack)|the Castle]], with the [[Valley of the Dead]] as its first floor.

==Levels==
The levels that compose Gehennom are described below.

===Valley of the Dead===
The Valley of the Dead's map is changed somewhat from ''NetHack'', and includes the previously-[[deferred]] [[Cerberus (EvilHack)|Cerberus]] and [[Charon (EvilHack)|Charon]]. The [[stair]] to Gehennom cannot be accessed until Cerberus is killed, nor can a hero [[level teleport]] or successfully use a cursed [[potion of gain level]] to leave the level until he is dealt with.

The [[Hidden Dungeon]] is accessible through a [[magic portal]] found in a specific area of the Valley—within the [[branch]] lurks [[Tal'Gath]], a very powerful [[Beholder (EvilHack)|beholder]] that must be killed in order to be able to [[genocide]] other beholders.

The hero's normal [[HP regeneration]] is suppressed while in the Valley of the Dead, though [[healing]] through other methods is not impacted.

===Filler levels===
Gehennom's filler levels are [[Gnomish Mines]]-style caverns levels filled with lava, and some of these levels will contain stairs or [[magic portal]]s to other dungeon branches:

* The magic portal to [[Vecna's Domain]] can be found on the first level below the Valley of the Dead.
* The stair to [[Vlad's Tower (EvilHack)|Vlad's Tower]] can be found anywhere from levels 34 to 42.

===Demon lairs===
The demon rulers and their lairs are randomized each game: there are three tiers of lair that become progressively more difficult, and each of them have their own set of maps and randomly-chosen rulers—the first two tiers host demon lords, while the third hosts a demon prince. The demon prince [[Orcus (EvilHack)|Orcus]] is not counted among these, as he is guaranteed to appear and is found in [[Orcus Town (EvilHack)|Orcus Town]]. In the presence of a demon ruler, the odds of escaping by [[teleportation]], [[level teleportation]] or [[quaffing]] a cursed potion of gain level are lowered to {{fraC|5}} for demon lords and {{frac|20}} for demon princes—additionally, if the hero attempts to level teleport past a demon ruler's lair, that demon will awaken and follow them.

The following tiers of demon ruler can be encountered:

* First tier: [[Juiblex]], [[Baalzebub]], [[Geryon]], or [[Baphomet (EvilHack)|Baphomet]]
* Second tier: [[Dispater]], [[Yeenoghu]], [[Lolth (EvilHack)|Lolth]], or [[Mephistopheles (EvilHack)|Mephistopheles]]
* Third tier: [[Asmodeus (EvilHack)|Asmodeus]], [[Demogorgon]], [[Tiamat (EvilHack)|Tiamat]], or [[Graz'zt (EvilHack)|Graz'zt]]

===Vlad's Tower===
{{main|Vlad's Tower (EvilHack)}}
Vlad's Tower is heavily revamped from [[Vlad's Tower|its appearance]] in ''NetHack'', and features far more dangerous [[Vampire (monster class)|vampires]] alongside an entrance that is blocked off by a deadly abyss.

===The Wizard's Tower===
{{main|Wizard's Tower (EvilHack)}}
The Wizard's Tower is also heavily revamped and made into a fully separate branch from Gehennom in comparison to ''NetHack''. There are still "[[Fake Wizard's Tower]]"-like structures within Gehennom, which have a much different appearance, and one of them hosts the two-way [[magic portal]] leading into the Wizard's Tower.

===The vibrating square===
The level containing the [[vibrating square]] is still a maze level as in ''NetHack''.

===The Sanctum===
{{main|Moloch's Sanctum (EvilHack)}}
Moloch's Sanctum has also been overhauled significantly from [[Moloch's Sanctum|its appearance]] in ''NetHack''. Here, the [[Amulet of Yendor]] can be found in the possession of the [[high priest]] of [[Moloch]]—once the Amulet is obtained, however, the up stair is blocked off, and another part of the Sanctum appears that must be traversed, with the demon prince [[Lucifer (EvilHack)|Lucifer]] guarding the path to [[Purgatory]].
