Dungeon

Dungeons are structures found below the Dirt Layer. At the bottoms of these respective layers, you can find the Boss Dungeons. Each room in a dungeon (minus the boss room) houses a hidden Treasure Chest that only appears once you kill all the mobs in that room. The Treasure Chest has a small chance to become a Special Treasure Chest for improved loot.
