For our Wrath Dailies series thus far, we've been trying to do them in groups. For example, we did the Kalu'ak dailies first, and now Adam is going through the Cooking dailies. I've decided to jump out of order for this one, because it's actually somewhat important beyond just another daily quest. This quest is actually training for Phase 3 of the Malygos encounter, in which you do battle with the Aspect of Magic from the back of a red drake.
You pick up Aces High! from Corastrasza on the Band of Transmutation, one of the floating platforms around The Nexus. If you've never done it before, head down to the Transitus Shield, there's a quest that will tell you exactly where to go. Practicing with this quest will make the fight much, much easier when you fight Malygos one day, because the abilities the Drake has in this quest are the exact same as the ones in that fight.
