Check your quest logs.
If you have either the scenario quest completed, or you’re on the final quest to return to Dalaran and talk to the Council of Six, you should be able to go turn it in and obtain the appearance.
Go to The Violet Citadel.
It’s possible that one of the Council of Six has the final mage tower quest available for you. Go to Dalaran, accept the quest, stand in the circle and have your weapon upgraded, and then complete the quest. This should award the appearance.
We apologize for the confusion. Thank you very much!
