Chest

Chest Blocks can hold 27 items, such as blocks and tools, and the items inside will never disappear. It is available on both the indev mode and infdev mode. A large chest can be made by putting together two chests and holds 54 stacks. Chests can be placed like any other block, but cannot be placed next to large chests. To obtain a Chest, you have to Craft it by using 8 wood blocks in a square shape. It cannot be opened if there is a block on top of it. Chests cannot be burnt. Destroying a chest with items still inside will yield the chest piece back again, along with any items contained in it.

Underground Chests
There is a rare chance of finding a chest underground now that contains somewhat random loot. So far the items appearing in said chests seem to be materials, tools, and saddles.
