###Location {#location} **Lab Vat** is found only in the [Mad Lab](/wiki/mad-lab). [Back to top](#top) ###Behavior {#behavior} The green Lab Vat (called Lab Bad Vat in the game files) inflicts [Hexed](/wiki/status-effects#hexed), [Stunned](/wiki/status-effects#stunned), and [Speedy](/wiki/status-effects#speedy) on players. These effects do not wear off until the player contacts blue Lab Vat (called Lab Good Vat), which instantly removes the effects. If the player is purified (ex. from the [Tome of Purification](/wiki/tome-of-purification)) after contacting Bad Vat, the Hexed and Stunned conditions will be removed, while Speedy will remain. This can be useful in rushing the dungeon. Lab Vat plays a critical role during the fight with the [Horrific Creation](/wiki/horrific-creation). The boss is invulnerable until players lure it into a pool of Bad Vat, which makes it vulnerable for a few seconds. Afterwards, the boss will run to a pool of Good Vat, revert to its original form, and the cycle repeats. Players can paralyze the boss when in the Bad Vat to prevent it from reverting.
