Pandemonium
| Pandemonium is an infinite realm of pain and suffering. While you can find a good deal of loot there, all these treasures are guarded by demons and even crueller demon lords. Many a hero, confusing confidence with megalomania, has died screaming in the barrage of torment and hellfire.
Pandemonium is endless. Portals there are found abundantly in the deeper parts of the main dungeon. Note that getting back might be more difficult. No fewer than five runes can be found in Pandemonium: • a fiery rune in the well-heated realm of Cerebov • a glowing rune in the contaminated domain of Mnoleg • a magical rune guarded by the arcane powers of Lom Lobon and his minions • a dark rune in the shadowy abode of Gloorx Vloq • a demonic rune, owned by a less famous lord |
| This gate leads to the endless halls of Pandemonium. Tales about successful lootings of these netherworlds are rare. Even the strongest and most experienced characters can die there. On the other hand, these halls contain several runes and lots of valuable items. It is much easier to get in than to get out. |
Pandemonium (or Pan) is an infinite demonic realm, populated by all manner of demons and randomly littered with any kind of treasure imaginable. One of the final branches of the game to explore (and a purely optional one), it contains endless treasure and experience, an unlimited number of Ziggurats for those players patient enough to hunt them down, and five runes of Zot:

Layout
Like the Abyss, Pandemonium is an infinite space containing endless opponents and loot, and you may explore it for as long as you like. However, unlike the Abyss, Pandemonium is comprised of individual, randomly generated realms, rather than an unmappable and limitless plain. Each realm is the size of an ordinary Dungeon floor, can come in a wide variety of layouts, usually contains one Pandemonium lord vault, and may contain a rune of Zot.
You may enter Pandemonium through any Pandemonium entry portal, which can generate on Dungeon:20-27. Traveling from one realm of Pandemonium to the next can be accomplished through a transit portal, several of which can be found on each floor. Bear in mind that once you leave a particular realm, you will never be able to return to it again, potentially resulting in the permanent loss of runes of Zot. Exiting Pandemonium can be accomplished through either an exit portal, or by instead entering a portal to the Abyss. Actual exit portals are very rare, appearing only on X% of realms, but they most commonly show up inside of a Pandemonium lord's vault. Abyss portals are somewhat more common, but do require you to then escape the Abyss in order to return to the Dungeon. Note that self-banishing via a distortion weapon is not an actual way out: after banishment, using the Abyssal escape portal simply returns you to the Pandemonium realm on which you were banished.

Be aware that each time you travel to a new realm in Pandemonium, you will be placed at an entirely random point. There is no guarantee that another portal will be anywhere near where you enter, or that you won't be dumped in the middle of a horde of powerful demons. If your character knows any buff spells, it is a good idea to cast them before entering any portal.
Monsters
Any given realm of Pandemonium is capable of throwing almost any demon above tier-5 at you, but each realm is inhabited by only a fraction of the possible demons you can encounter. This means that you will be encountering tier-1 and -2 demons as a regular occurence; don't even consider entering Pandemonium unless you are comfortable with this.
More dangerous than the hell sentinels and fiends, however, are the Pandemonium lords. These are essentially randomly generated uniques, each of which has its own resistances, attack brand, and spell set. They also tend to generate along with a very large horde of demons appropriate to the floor, making it a fairly common occurrence to come across multiple sources of torment, heavy elemental damage, and a powerful unique all at once. Always examine a Pandemonium lord before engaging it in combat, and always act carefully; there's a chance that it'll be a pushover, but it's just as likely to be one of the deadliest opponents in the game.
The Runes
Although players can conceivably acquire unlimited experience and treasure by farming Pandemonium realms endlessly, doing so serves little purpose; it is dangerous enough that most players capable of handling it already have all they need to clear the rest of the game as well. Searching for potions of cure mutation or items to open a treasure trove may be rewarding, but bear in mind that there are plenty of sources of bad mutations and item destruction here as well. Farming Ziggurats is an option, but one that only experienced players should even consider. The main reason for anyone to enter Pandemonium is to retrieve its five runes of Zot.
The Demonic Rune
While exploring random Pandemonium realms, the demonic rune of Zot will occasionally generate within the vault of a Pandemonium lord. This means you will always have to deal with a powerful horde of demons to get it (or at least to apport it and run). Not all Pandemonium lords will have it in their possession though; there is an 11.1% chance that any normal vault will contain it, and a 100% chance for three particular vaults:
- Hellion Island - A square of terrain, surrounded by lava, populated by dozens of hellfire-flinging hellion, all led by a single Pandemonium lord. Extremely deadly.
- Eyes of Draining - Eight careful spaced eyes of draining, locked away behind grates, will devastate your MP as you deal with a Pandemonium lord and its cohorts. The rune is locked away in a ninth cage in the center.
- Smiting - A hallway lined with smoke demons, locked away behind grates. These will smite you repeatedly as you deal with the horde inside.
Once you have acquired the demonic rune, it will never appear again. If you fail to acquire it in a given realm before leaving, however, it will still appear in a future realm.
Unique Realms
Along with the endless random realms of Pandemonium, traveling from realm to realm will eventually bring you to four unique realms, each of which is ruled over by a unique Pandemonium lord. Upon entering one of these, you will receive a message declaring whose realm you've entered. You can only enter each of these realms once per game; once you've left these realms, they are forever lost to you, taking any unclaimed runes with them. As such, it is best to delay entering Pandemonium until you are confident in your ability to take on all four challenges.
It is entirely possible to steal these runes without killing the unique Pandemonium lords which guard them. Clever use of fast movement speed, scrolls of magic mapping, teleport control, Lee's Rapid Deconstruction, Shatter, and Apportation can allow you to snag the rune quickly and (relatively) safely. That being said, failure to kill a unique Pandemonium lord whose rune you've stolen will add that lord to the list of enemies which may attack you during your ascension.
The Fiery Rune: Cerebov's Realm
Searing heat pours from the floors and walls of this place. The mighty Pandemonium lord Cerebov resides here.
The fiery rune of Zot is guarded by Cerebov, a powerful giant and master of Fire Magic. His realm is primarily made up of long hallways, but roughly half of the map will consist of his massive metal fortress. Fully exploring the fortress will reveal several small treasure chambers, and killing Cerebov will reward you with the sword of Cerebov. Max out your fire resistance, and see the Cerebov article for further advice.
The following monsters are found in Cerebov's realm:
4 
Orange demon.
4 
Red devil.
R 
Efreet.
3 
Sun demon.
2 
Balrug.
& 
Cerebov.
The Glowing Rune: Mnoleg's Realm
The air here is shimmering with an eerie glow. The mighty Pandemonium lord Mnoleg resides here.
The glowing rune of Zot is guarded by Mnoleg, a chaotic jester who delights in mutating his foes. His realm offers wide hallways and occasional doors, while his vault is made up of several wide diagonally crossing hallways. Apart from the rune, there is no guaranteed treasure to be found here. Use a source of mutation resistance, a ring of sustain abilities, and an amulet of stasis while here, and see the Mnoleg article for further advice.
The following monsters are found in Mnoleg's realm:
w 
Brain worm.
4 
Chaos spawn.
3 
Neqoxec.
2 
Cacodemon.
& 
Mnoleg.
The Magical Rune: Lom Lobon's Realm
You sense a powerful magical presence. It is not pleased. The mighty Pandemonium lord Lom Lobon resides here.
The magical rune of Zot is guarded by Lom Lobon, a powerful archmage demon who can inflict devastating amounts of electricity and cold damage. His realm is made up of crossing vertical and horizontal hallways and small chambers, while his vault is a massive green crystal structure, much of which is submerged in deep water. He and the rune reside in the large "X" in the center of this structure. Apart from the rune, there is no guaranteed treasure to be found here. Bring some electricity, poison, cold, and magic resistance, and see the Lom Lobon article for further advice.
The following monsters are found in Lom Lobon's realm:
4 
Hellwing.
2 
Green death.
& 
Lom Lobon.
The Dark Rune: Gloorx Vloq's Realm
Shadowy figures dance across your vision. The mighty Pandemonium lord Gloorx Vloq resides here.
The dark rune of Zot is guarded by Gloorx Vloq, a hooded demon with spectacular speed and access to all manner of devastating Necromancy. His floor is filled with open chambers and wide hallways, while his vault is a large chamber filled with pillars, executioners, and a back chamber containing the rune. Apart from the rune, there is no guaranteed treasure here. See the Gloorx Vloq article for further advice.
The following monsters are found in Gloorx Vloq's realm:
1 
Executioner.
3 
Soul eater.
& 
Gloorx Vloq.
Preparation
Due to the very diverse monster set you will face in Pandemonium, you should try to be ready for a little bit of everything before entering. The more powerful you are in every field, the better your chance of survival. That being said, it is strongly recommended you bring at least the following:
- Fire resistance, preferably rF+++ when facing Cerebov.
- Cold resistance, preferably rC+++ when facing Lom Lobon.
- A source of electricity resistance when facing Lom Lobon.
- A source of poison resistance when facing Gloorx Vloq or green deaths.
- Any source of torment resistance for dealing with fiends, tormentors, and Gloorx Vloq.
- Mutation resistance when dealing with neqoxecs, cacodemons, and Mnoleg.
- A ring of sustain abilities/several potions of restore abilities/several royal jellies when facing Mnoleg's realm.
- Methods for healing/teleporting/blinking to safety.
- A source of Haste.
- Some inventory space for the loot you come across.
- A wand of digging.
Of course, you don't necessarily have to gather all five runes in a single trip. Leaving Pandemonium and then returning after you've resupplied or leveled up has no punishment, and any of the preset realms you have not yet visited will still be waiting for you when you return. Just be aware that you do not get to choose when you find any given preset realm, or even an exit.
History
In 0.14, each Pandemonium rune you pick up increases your odds of finding an exit. Pandemonium will also feature a new set of demonspawn monsters.
Prior to 0.10, self-banishing via a distortion weapon was an effective way to escape, equivalent to using a portal to the Abyss.
Prior to 0.9, there were infinite demonic runes of Zot. The record for most collected came in at over 250.
Prior to 0.7, scrolls of magic mapping and Lugonu's Gate yourself to the Abyss ability were both disabled in Pandemonium.
Prior to 0.6, you received no warning message upon entering the realm of a unique Pandemonium lord.
