Dungeon Guardian (Before defeating Skeletron).After the Old Man has been freed and becomes the Clothier, Skeletron can be summoned again using a Clothier Voodoo Doll and killing the Clothier. Entering the dungeon below 0 Depth without first defeating Skeletron will cause the Dungeon Guardian to spawn, which can kill a player on contact. During the day, he will say to wait until night to talk to him. Skeletron is the guardian boss summoned by talking to the Old Man standing outside the dungeon entrance at night. To gain access to the dungeon, Skeletron must first be defeated. The monster spawn may be abnormally high as there are Water Candles spread throughout, so try to break them while traversing the dungeon to keep the rate down. The dungeon has a large number of unique monsters. However, since the Goblin Tinkerer and the Wizard can be found anywhere underground once their requirements are fulfilled, they may also spawn in the dungeon, and can be unbound the same way. Only one NPC can be found anywhere within the dungeon, and will be bound until the player right-clicks on them and untie them, and that is the Mechanic. Placing blocks or platforms over them is recommended. They can be mined, but are harder than the dungeon brick. Spikes line much of the dungeon making simple traversing dangerous. There are many rooms branching from the labyrinth where a great deal of loot can be found and can be a good resting place as monsters only have one access point to the character. It is highly recommended that every character have a Magic Mirror or potions for quick escape, as getting out is often more difficult than getting in as a result of needing to go up. The winding nature works to make monster spawns unpredictable, creating many 'ambushes' from above.

The dungeon zig-zags down from the entrance to a larger, labyrinth like section where the majority of the loot can be found. Also, to remove them, you must start at an edge and work your way inwards.

Dungeon background walls also need a high tier hammer to remove, but also, cannot be removed before defeating Skeletron. It requires Nightmare Pickaxe/ Deathbringer Pickaxe or higher to mine and is immune to explosives. Upon gaining access, the Clothier NPC will be freed and the player can then roam about fighting deadly enemies, dodge numerous traps, and discover powerful loot.Īs of 1.3.0.1, after defeating Golem, Cultists will spawn at the dungeon entrance and killing them will summon the Lunatic Cultist (which will then initiate the lunar events and Moon Lord). Since the dungeon guardian can kill the player in one hit, and is extremely fast, it is highly recommended that one does not enter the dungeon before defeating Skeletron. It is the home of the pre hardmode boss, Skeletron, who will only spawn at night when talking to the Old Man but if attempted to enter before defeating Skeletron the player will face the Dungeon Guardian. At world creation, the dungeon is randomly formed from one of three Dungeon Bricks and walls (Can come in blue, green, or pink variants). It spawns on the opposite side of the world as the side the dungeon was on in the last world created, and on the same side as the Snow Biome. The Dungeon is an enormous structure found close to the edge of the world opposite of the Jungle, spanning many layers deep, usually all the way to The Underworld. A bug where the top layer of a small world spawns below the entrance to a dungeon.
