How to destroy Level-80 boost taking my shared inventory slot hostage?

[SpaceMarine.1836]

Hi,

I bought EOD and I would like to use the shared inventory slot that came with it, but the slot is taken hostage by Level-80 boost, which can not be removed from it, and can not be destroyed. I bought additional character slots for my account, so I have 9 total, each for every profession, and I already have 9 level 80 characters I've invested a lot of time into. I obviously won't sacrifice any of them, and I don't have any empty character slot to make a dummy character to waste this boost on. 

So I am in a situation where I have to pay 800 gems ransom for a Character Slot Expansion so that I can make a new temporary character to be able to destroy the boost. Does anyone have any better idea how to do this? I could really use that shared inventory slot.

Thanks in advance.

You can consume it on a level-80 character. You will get some armor food and boosters after which it is gone and your shared slot is free to use.

It would have been nicer if you could just toss those L80 boosters in bank for later use but alas.

In the future...the Wiki (link above) is a great resource for all thing Guild Wars 2.  Yes, use it on an existing L80 character - reap the rewards.  https://wiki.guildwars2.com/wiki/Level-80_Boost#Contents
