Dungeons consist of a network of rooms, containing various types of monsters based on the theme of the dungeon. The last room will contain one or more boss enemies, which may drop special items. These items may be considered as inferior, or extremely useful.
To reach a dungeon, it is necessary to kill certain enemies, which will randomly or systematically open the entrance to that dungeon. Any player can enter to fight the monsters inside, usually by clicking “Enter” or using the interact key when standing on an entrance.
Some dungeons have a multi-stage layout with portals connecting different stages. Details of these are described on the individual dungeon pages.
All portals stay open for 30 seconds before vanishing, except for the Locked Wine Cellar Portal which will remain for two minutes if not opened. An unlocked Wine Cellar portal remains open indefinitely.
Passing through the exit portal of most dungeons results in a completion statistic being counted on that player’s character. The Tunnel Rat fame bonus is awarded to characters that have completed all the requisite Tunnel Rat dungeons. These are indicated in the tables below. Not every dungeon tracks a completion stat - the dungeons that have no functioning counter are indicated with NC. Some dungeons have no completion/exit portal, these are indicated by NP.
Most dungeons have a player limit of 65 players. Attempting to enter a full dungeon will only result in a “Dungeon is full” message appearing in the chat. The exceptions to this limit are:
|Candyland Hunting Grounds||3||N|
|Cave of a Thousand Treasures||3||N|
|Abyss of Demons||4||Y|
|Manor of the Immortals||4||Y|
|The Puppet Master’s Theatre||4||N|
These dungeons drop from enemies which can spawn up to once per realm. With a few exceptions, they are generally more difficult than Realm Dungeons and include some of the hardest dungeons in the game. All of the dungeons listed below drop at a guaranteed rate.
Note that the enemies listed under “dropped” do not include seasonal reskins, which can be found here.
|Davy Jones’s Locker||4||N|
|Lair of Draconis||5||N|
|The Crawling Depths||5||N|
|Tomb of the Ancients||5||Y|

Wormholes are portals to four alien worlds. None of these are required for the Tunnel Rat fame bonus.
Once the Alien UFO is defeated, Commander Calbrik orders his soldiers to retreat and leave a malfunctioning wormhole generator behind. Several wormholes subsequently appear across the realm, and are visible on the minimap as colored dots. Each wormhole is guarded by a small party of enemies from the dungeon.
Two minutes after the realm closes, all players within the realm (not in dungeons) will be transported to Oryx’s Castle, which consists of multiple areas. None of these are required for the Tunnel Rat fame bonus.
|Oryx’s Castle||No portal||Automatically transported into it 2 minutes after realm closes||4||NC|
Locked portal is a guaranteed drop
Must be opened with a Wine Cellar Incantation
|Court of Oryx||
|Lair of Shaitan||5||N|
|Puppet Master’s Encore||5||N|
These dungeons are a more difficult version of the boss room of their non-heroic counterparts, although they do provide better rewards in compensation. All heroic dungeons do not allow pets. None of these are required for the Tunnel Rat fame bonus.
Both heroic dungeons used to have a chance of dropping from the bosses of the respective non-heroic dungeon (Septavius the Ghost God and Archdemon Malphas) but they currently do not drop, meaning they are only accessible from keys. However, the keys are not currently sold in the Nexus.
Special Event Dungeons are dungeons that were only available for a limited time. None of these dungeons are required for Tunnel Rat.
