Black Plague Quest

[Black Rose]

I found this quest at allakhazam for min.lvl 37 all classes.
Black Plague Quest (http://camelot.allakhazam.com/quests.html?realm=Albion&cquest=1793)

Together with Jag I was able to kill maloch the cook in DF for the last step.
The reward was the "stoppered wondrous potion". Potion linky (http://camelot.allakhazam.com/item.html?citem=9982)

My problem is, that I dunno how to use this item.
I put it on my quickbar, but can´t use it. :unsure:

Any ideas? :unsure:

Put it in your quickbar and use your 'Use' key. This potion will allow you to heal yourself or anyone one time. I wonder if you can bring this to the recharger or if it's a one time only thing. :WTF:

[OUTLAWS The Machine]

Put it on your quickbar, hold down your "use" key (E is default), then click on the potion on your quickbar.

ahh, I used shift + E and klicked on the item... :oooo:
(I got always the message:you can´t fire or ready this item)

Big thanks you two :drink: wub
