Dungeon

The Dungeon is an enormous building found close to the edge of the world opposite of the Jungle, spanning many layers deep, usually all the way to The Underworld. At world creation time, the Dungeon is randomly formed from one of three dungeon bricks, and one of three dungeon brick walls. The color of the bricks does not always match the color of the walls.

Dungeons are filled with chests containing rare and powerful items as well as unique decoration items. They also include a number of unique monsters listed below. The dungeon is always on the opposite side of the world from the Surface Jungle.

To gain access to the Dungeon, Skeletron must first be defeated. Skeletron is the guardian boss who is summoned by talking to the Old Man standing just outside the Dungeon entrance at night. If you talk to the Old Man during the day, he'll say to wait until night to talk to him. Entering the Dungeon without first defeating Skeletron will cause the Dungeon Guardian to spawn, which can kill the player in one hit.

It is recommended to be at an mid-to-end-game level to access the Dungeon, as enemies in the Dungeon will deal up to 20+ damage even with armor, and efficient navigation of the Dungeon requires a Grappling Hook or movement-enhancing accessories. Loot is spread evenly throughout the Dungeon, so loot further down is not necessarily better.



Artificial Dungeons
It is possible to create an artificial Dungeon by placing Dungeon Bricks and Dungeon Walls. In order to be in a Dungeon area, the player needs to be next to at least 250 Dungeon Bricks and have Dungeon Walls behind them. The music will change to the standard Dungeon theme within a properly constructed artificial Dungeon. Note that the Dungeon area doesn't need to be enclosed in any way.

Keep in mind that monsters will only spawn offscreen, so the Dungeon needs to be large enough to allow for an offscreen area where Dungeon monsters can spawn. Also, Dungeon monsters will only spawn below 0 depth, as read by the Depth Meter. If Skeletron has not yet been defeated, players should be aware that the Dungeon Guardian will spawn in the artificial Dungeon.
