I just got this email today from Funcom.
I got this for signing up for the forums a month ago. They were using this as a promotion to get people to sign up for their forums.
You have been a long and thrustworthy participant in our community, and as such we would like to thank you for helping us form Age of Conan into the marvelous product it is today. The last weeks has seen some serious enhancment to the game, and with the release we will be opening several new areas and neverbefore seen content in the launch version of the game. What and where it is? You have to find out for yourself!
As a sign of gratitude for your aid, we are pleased to offer you the in-game item used by those loyal to King Conan: The Drinking Cape. This item will allow your characters (one game account only) to free of charge demand the very sought after alcholic drink of "Ambrosia" - free and in unlimited supplies for life! After having claimed your cape, merely find one of the kegs in the finer Inns of Hyboria and click it whilst wearing your cape to receive your drink.
To register your cape, log in to your account page by https://register.ageofconan.com clicking here and under the option "Use a Key" - enter this key:
Once this has been done, use the command "*******" inside the game to claim your in-game items. These items work for all the characters you create on your account. Note that all in-game items are only available on full accounts, and do not work on pre-order, buddy or (later) trial accounts.
Note that this item will not be made available again at later dates - so wear it with pride!
Behold the drinking cape!
