The Labyrinth Island

The Labyrinth Island is an island that can be travelled to via a Ship constructed with a Ship's Helm, and must be discovered with a Pirate's Telescope purchased from the Pirate NPC.

It is a small island, smaller than a small world and it is guaranteed to be generated for each world. When travelled to by ship, the ship will spawn on the left side of the island.

In the centre of the island, there is a labyrinth structure that is similar to the Dungeon, however unlike the dungeon you do not need to defeat any bosses before entering.

Inside, there are 3 layers. The first layer, is similar to the Dungeon, and is made solely out of Blue Dungeon Bricks. Regular dungeon enemies will spawn, as well as Labyrinth Keepers. This area can be travelled to in Pre-Hardmode, but no enemies will spawn until Skeletron is defeated. The passage to the second layer is blocked with Runewall that will disappear upon the world becoming hardmode. The passage and the second layer is made completely out of Labyrinth Bricks that cannot be mined without a Picksaw dropped by Golem.
