Ender Chest

Ender Chests were added in Snapshot 12w21a. An Ender Chest works in a similar fashion to a standard Chest but shares the same inventory to multiple Ender Chests.

The chests can be created by surrounding an Eye of Ender with Obsidian. , and emits a particle effect similar to that used by an Enderman and by a Nether Portal, as well as slight light level increase.

Ender Chests do not have a Double Chest variant and can be placed adjacent to one another.
