Shadow Dimension
Exclusive to: 
The Shadow Dimension is a special storage space that can be accessed by Shadow Chester, Magician's Top Hat and Magician's Chest.
The Shadow Dimension has an inventory of 12 slots. Things that are put inside can be taken out from other Shadow Dimension containers. In addition, edible items in it spoil 1.5 times faster. The irreplaceable items cannot be stored inside Shadow Dimension, such as Celestial Orb and Eye Bone. The loss of any container linked to the shadow dimension does not affect the items stored inside, even if there are no such containers left in the world. In this case, the items can only be accessed again as soon as a new Shadow Dimension container is created.
There is one Shadow Dimension per shard: one on the Surface, one in the Caves. The shadow dimension cannot be used to transport items across shards.
The Shadow Chester and Magician's Chest can be used by all players, but only Maxwell can use a Magician's Top Hat.
