Level-80 Boost & Shared Inventory Slot
You can use the boost on a level 80 character and get all the stuff it gives.

Indeed, if you use it on a lvl 80 character, you gain all the material benefits of the boost. Since you don’t have a character slot, maybe that is the way to go. Or you could buy either a character slot or a shared inventory slot. Unless you are maxed out, of course.
Until you use the Level 80 boost, the free shared inventory slot is “locked” out. That is so you can’t accidentally delete the boost.
Details on what the Level 80 boost does (it’s not just a level 80 scroll like the level 20 or 30 ones) is found in the wiki.

Sure, I get that I can just use it on an 80 to free up the shared inventory slot, but that strikes me as a bit of a waste. What if I want to save the Boost, say for the next expansion and Tengu (hey, I fella can dream).
My gripe remains: the only way to remove that Level-80 Boost from the Shared Inventory slot is to use it, when I can see no reason why I can’t simply put it in my bank until I actually do want to use it.
Just not the way they implemented it. No storing of the Boost, except in the Shared Inventory Slot. Mine still sits there. Can’t really gripe about something given free of charge.
