Laborratory is the seventh challenge stage in Vampire Survivors. This stage can be unlocked by collecting a total of 33 Rosaries.
The hyper mode for this stage is unlocked by default.
Alternatively, Laborratory can be unlocked in the Forbidden Scrolls of Morbane by casting the Spell "divineassault".
Description[]
Formerly the foundry where the famed anti-vampiric weaponologist Santa Ladonna created many trinkets, the Laborratory now lies abandoned. Whispers echo that Santa fled from this makeshift workshop when her experimental alchemy somehow opened a door that was never supposed to be breached.
Effects[]
This stage features interactable rooms, winding corridors, and a train track found by going south. Each area has its own effects, which could be to the player's benefit or detriment. Levers are a stage prop that can be found throughout the stage, which, depending on Luck may spawn weapons, passive items, or swarms of tough enemies that rush by the player. Silver chests can be dropped by bosses before 10:00.
Levers[]
On this stage, levers appear at different locations on the map. Walking over these levers causes them to flip over, resulting in various effects, which include spawning a pickup, weapon, passive item, or enemy wave.
Some lever effects are unique to the location where they are found. Below are the possible locations where a lever can spawn.
- Central Room: The largest room and the nearest to the player's initial location. Located by going north of the central area. The levers found here may produce the following:
- Santa Javelin / Arma Dio
- Metaglio Left / Metaglio Right
- Swarm of Yellow Reaper Trainees / Trinacria / Fallen Cherubbello (self-destructing)
- Danger Room: This room is located west of the central area and is characterized by the danger signs on the wall in front of the room. The levers found here may produce the following:
- Cross / King Bible
- Spellbinder / Clover
- Swarm of Jellyfish / Dust Elementals / Musc Muscs
- Electricity Room: This room is located east of the central area and is characterized by the high voltage warning signs displayed on the front of the room, which can also be found on the walls of the corridor leading to this room. The levers found here may produce the following:
- Santa Water
- Silver Ring / Gold Ring
- Swarm of Jellyfish / Dust Elementals / Musc Muscs
- Near the Railroad: The railroad located south of the stage—specifically, the walkway below the rails, and the platform by the corridors—frequently spawns levers that differ from levers found elsewhere in that they summon a train called Take Us Away rather than items or enemies. This train damages any enemy that it collides with on its path.
Additionally, levers may spawn pickups that are not room-specific and can spawn in any room type (not including the levers near the railroad).
Levers can spawn at the aforementioned locations off-screen, once every 20 in-game seconds. Each room may spawn up to 5 levers at once, but the area by the railroad can have levers up to the max destructible count of the stage (which is 12). The favorability of an effect and the spawn rate of the levers are affected by Luck.
The effect of Mad Groove (VIII) does not work on levers.
Items[]
The following items can be found in this stage:
Pickups[]
Levers found inside rooms can spawn a Coin Bag, Vacuum, Rosary, or Little Clover.
Stage Items[]
These items can be found by flicking the levers found inside rooms. Refer to the previous section for their locations.
Weapons[]
Passive items[]
The 4 hidden stage items can also be found here, which can be found without the Yellow Sign unlocked.
Waves[]

Traps[]
Stepping on "trap pizzas," which appear as circular plates on the ground, triggers an unavoidable map event, selected from 9 predetermined options. These traps can be discovered inside rooms, in front of lever spawn points, or along passageways leading to other rooms. The traps require a minimum cooldown of 15 seconds before they can be activated again.
