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.

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.


Lab Key The Lab Key is available in the Nexus for 50 Realm Gold.


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

  • This dungeon was added in Build 123.5.0.
  • The bosses drop the “Mad Scientist Sorcerer Set“.
  • This dungeon does not have to be completed to earn the ‘Tunnel Rat’ fame bonus.
  • Each part of the sorcerer set has a specific “rarity”. The higher the feed power, the rarer the item is, the Experimental Ring being the most common, and the Scepter of Fulmination being the rarest.

There are many monsters that inflict stunned and confused. 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 the last two Tesla coils.

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

It is a source of Potions of Defense and the UT Mad Scientist Sorcerer’s set, consisting of the Conducting Wand, Scepter of Fulmination, Robe of the Mad Scientist, and the Experimental Ring. The portal to the dungeon (dropped by the Flying Brain) drops at a very low rate and is available as a key in Nexus for 100 gold.


Out of all these enemies, the Crusher Abomination takes the title for being the most dangerous in the dungeon, it shoots 3 wide bullets in a quarter-circle pattern and before it is damaged in anyway the bullets will be small in size and will not be as much damaging, however as you do more and more damage to it, it will increase in size and also increase the size of the bullets. In it’s final stage the 3 bullets are massive and highly damaging. Although a person with a decent dodging skill maybe able to dodge them, it is advised to be cautious. Circling the Crusher Abomination can be done if there is enough space, but most of the time you won’t find that much space in Mad Lab.

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.
-In the confuse rooms, you can angle your screen so that you move with a+s or w+d. When you are confused the controls 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.
