Here are a couple of neat tricks that can be useful in Minecraft. Check here to find out what an ender chest and the eye of ender can do for you.
An ender chest holds items just like normal chests, but shares that inventory with other ender chests that are placed anywhere, including in other dimensions such as the Nether or the End (the inventory is only available to the player who created the chest). When an ender chest is broken, its items do not drop. You can retrieve them at another ender chest or by creating a new ender chest.
You can then stockpile items that are easily accessible at all bases or houses. Though ender chests are explosion-resistant, you can break them with a pickaxe or enderdragon.
Ender chests don’t work with hoppers, droppers, command blocks, or pistons. They’re treated as inventory of the player and not as a block.
The only downside is that an ender chest is far more difficult to make than a chest, requiring 9 blocks of obsidian and an eye of ender. Obsidian can be mined at places where water meets lava throughout the game. It can also be obtained on the Nether Portal, or in unlimited form in The End region on the platform that is created each time you enter The End.
Eye of ender is used to locate end portals and as the final ingredient in crafting an ender chest. To locate an end portal, simply hold and right-click the eye to send it into the sky, toward the portal, with a trail of purple dust to follow. After you find a portal, 12 eyes are needed to activate it.
To craft the eye of ender, place blaze powder and an ender pearl (dropped by Endermen when they die) anywhere on the grid.
