Aion's double run of Shugo Kingdom Adventures, the limited-time instance that offered some pretty nifty rewards to those who chose wisely? If so, you might be glad to hear that Aion has introduced a new version themed for the holiday: Nightmare Circus. As before, only special skills can be used within the instance and only Daevas level 30 and above can enter.
This time, however, instead of becoming a Shugo, players will be transformed into a bear-like Khum'gom. Even more power can be obtained if players transform into a Nightmare Circus Harlequin using an item available via quest and in the store. Also, anywhere from two to six players can participate. The instance consists of three stages, and rewards can include exclusive costumes and wings, dyes, consumables, manastones, and much more. For a full accounting of all the possible prizes and a breakdown of each stage, check out the official announcement. But if you want to get in on the event, you'd better hurry -- the Nightmare Circus is in town for only two weeks and packs up November 6th, 2013.
