Mad Lab

Mad Lab
Difficulty: 5Difficulty: 5Difficulty: 5Difficulty: 5Difficulty: 5

The Mad Lab is a medium-high level dungeon that is a source of Potions of Wisdom, Potions of Defense, and the Mad Scientist Sorcerer UT Set, and two pieces of the Horrific Sorcerer ST Set: the Grotesque Scepter and Horrific Claws.

This dungeon is intended for high-level players (Suggested level: 20) because the enemies and bosses can do significant damage.

Entrances to the Mad Lab are uncommonly dropped from Flying Brains.

This dungeon does not have to be completed to earn the ‘Tunnel Rat’ fame bonus.

The Realm Eye says:
The Mad Lab was transported from a dimension far removed from ours. The methods of alchemy practiced within are unlike any other known science.
The technology stolen from the laboratory was eventually repurposed to transform passive creatures into powerful sidekicks.
The pets your kind uses as allies would not be possible without Dr. Terrible’s highly advanced scientific tools.


Lab Key The Lab Key is available in the Nexus for 100 Realm Gold.


See the Mad Lab Guide for a complete walk-through on the dungeon and all its enemies.

Out of all these enemies, the Crusher Abomination takes the title for being the most dangerous in the dungeon. It has a wide, quarter circle-patterned shotgun of 3 bullets that steadily increase in size and damage as the Crusher Abomination’s HP decreases. Although a person with decent dodging skill may be able to avoid the bullets, caution is advised. Circling the Crusher Abomination can be done, but often there won’t be enough open space to do so.

Tips and Strategies

  • When there are two paths, the one that is blocked off by a wall is always the correct path towards the boss room. Sometimes the correct path isn’t blocked off, but an incorrect path is never blocked off. There is only one room that is an exception to this rule, being the fact that it contains multiple blocked off paths (but the incorrect ones will immediately have a dead end).

  • In the confuse rooms, you can angle your screen so that you move with A+S or W+D. When you are confused the control for A is swapped with S and W is swapped with D, so down-left and up-right remain the same whether confused or not.

  • Be careful when you get confused as you might step in an acid pool or into other mobs or other slow-moving, high-damaging projectiles.

  • This dungeon was added in Build 123.5.0.
  • Before build 123.5.1, melee characters without a Crystal Sword could not complete the secret boss quest of the dungeon solo because 4.5 or more tiles of range are needed to destroy Tesla Coils in cross-shaped rooms lined with a Green Lab Vat. It was not possible to hit the coils without entering the liquid and becoming stunned.
