Laboratory

The Laboratory is a structure that can be found in the underground layer. It is similar to the Jungle Temple, as only one can spawn in a world, it has multiple enemies, and it contains an altar with a boss battle.
The Laboratory is split into three sectors. The first one can be entered with the White Key, which drops from Skeletron. The second can be accessed with the Grey Key, which drops from all Mechanical Bosses. The third and final sector requires a Black Key, which drops from Golem, to enter.
The structure is formed from Pale Bricks. Multiple furniture items can be found, including Alchemy Tables from the Dungeon. Pale Chests can be found here as well.
Each sector houses a new enemy to battle. The first spawns Tainted Brawlers, the second adds Amalgamated Followers, and the third introduces Twisted Serpents. The third sector ends with a large room where the Emergency Button resides, which summons the boss of the structure.
The building also has some traps. Axe Traps, Wind Pipes, and Experimental Dart Traps can all be encountered in the building and mined after defeating the boss of the Laboratory.
