Account Items Clarification.
The items that you get from Wildstar Deluxe Edition or Beta/PTR testing are in the Account Inventory, which is located at the bottom left of your UI, next to the clock.
Boom Boxes have anywhere from 3 to 123 of these in your Account Inventory. Check out our guide to them right for all the details!
Everything Else in the Account Inventory can be claimed by any toon you make. If you make 20 alts, they can all claim these items when you reach the appropriate levels.
