Pyramid

The Pyramid is a structure added in the 1.2 update.

Pyramids are made of Sandstone Blocks and are rarely created during world generation in Desert Biomes. An experiment generating 100 small worlds using version 1.2.0.3.1 showed an 83% chance of having 0 pyramids, a 15% chance of having 1 pyramid, and a 2% chance of having 2 pyramids. They can contain treasure rooms with a chance of unique loot like the Flying Carpet, a Sandstorm in a Bottle, the Pharaoh's Mask and the Pharaoh's Robe.

They usually spawn partially exposed to the surface, although mining or the use of a Spelunker potion is often better to reveal them. In addition to unique treasures, they offer unique decorative banners and a variety of coins stuffed in bags lying on the floor which can be broken with a pick of any kind. The coin hoard can be considerable, especially if bags of gold coins are found. Pyramids can also be found in other biomes, reportedly being found in the middle of the jungle.
