Dungeon

The dungeon is one of the highest level "biomes" in the game. It is either on the right or the left side of the map and can be in a variety of colors, including: Green, Pink, Purple, and Blue. You can't enter until Skeletron has been defeated. If you try to enter without defeating him, he will either one-hit you (day), or multiple Skeletron skulls will appear and attack you normally (night). There are certain Dungeon only items found in chests. There is a high chance of finding chests and life crystals in a dungeon.
