Using the Key, Lock, and XP Transfer Together
Securing an XP Storage Block
Craft a Lock and attach it to an XP Storage block to restrict who can open it. Craft a Key to match and keep it in your inventory. With the lock in place, other players cannot withdraw the XP you have banked.
Place your locked XP Storage somewhere protected, such as inside your base, so the block itself is not broken. The lock handles access; the walls handle everything else.
Moving XP with XP Transfer
XP Transfer lets you shift stored experience between locations. Use it when you want to consolidate XP from several XP Storage blocks into one, or move a banked amount to a different part of your base.
Before moving anything, use the XP Storage Inspector on each block to confirm how much XP it holds. That way you know exactly what you are transferring and can verify the amounts afterward.
Keep your Key on you whenever you plan to open a locked block. If you misplace it, you will need to craft a replacement before you can access the stored XP again.
The XP Storage Handbook documents how these items fit together. Consult it in-game whenever a recipe or interaction is unclear, and build your storage room around the blocks and items you actually use most.
