Pocket Chamber - TPA alternative

v21.3.1.0-h1 -> MC v1.21.3, Mod v1.0, hotfix 1

Take your friends with you

 
This mod makes the Stasis Chamber a portable item that you (or your friends) can take with them.  

They went exploring and found a nice place that you need to walk to?
-give them a Stasis Chamber with your ender pearl in it and they can take you with them.

Throw an ender pearl at the block to insert your ender pearl into it.

You can check the item tooltip if the chamber is occupied:

 
And then just right-click to teleport them :)
