To kick off your wing-hunting expedition:
You must be level 5 to complete this quest.
1. Talk to the Strange Traveler and receive the battle quest [Ye Olde Christmas Energy]. The little guy will allow you to play the tower defense mini-game for Christmas Energy. You’ll need 10 Xmas Energy for the wings, so stock up!
2. Complete the Storyline [Event: 2012 Christmas] to obtain the second required item: the Christmas Emblem.
3. The third and final item you need to claim your pair of Devil Wings is the Fancy Christmas Cake, which can only be found in the [Christmas Gift Box].
4. Once you’ve got 10 Xmas Energy, 1 Xmas Emblem, and 1 Fancy Cake, turn them all in to the Strange Traveler for your glorious (and ultra-rare) pair of Devil Wings!
