Tragic Beauty asked me if I could get on the forum and talk about how I got my AA's. First and foremost, I play a lot . I saved up about 60 my EP potions and waited for events to come along that offered AA's I wanted. It was especially helpful when one of the events offered 2 Velvet dreams if you progressed far enough. I got my explosive demon during an event too but had to find a trade on the AH to evolve it. My best advice would to be to know what you want. Don't burn a bunch of EP on an event unless you get a good mob or 2 or finish well in the rankings. Now I am trying to keep an eye out for more AA impulse demons offered in events and maybe by this time next year I will have them all lvl 150. Well, it's not fancy but that's what I've done. I hope it helps.
