Portal Chests are utility blocks. With it, you can transport items ANYWHERE in your world (as long as there is one more in the world, so you can transfer it to every portal chest)!
How to MakeEdit
Go to your closest portal (or any portal) and be sure to bring with you:
1 Golden Chest
1 Portal (made at a workbench, a toolbench, OR a woodwork bench)
100 Time Crystals
And just remember; you need to have the diamond upgrade.
Why it`s usefulEdit
If another Blockhead or a friend is at another (far) part of the world, you can use portal chests to get it there, aslong as you AND that Blockhead/Person has one. It`s almost like a mailbox.
