Well, it’s been a while since we have done any of the Kaos Doom Challenges, but is changing. With the levels coming to an end, and with Lias and I getting near the end of Arena Battles we are not starting to focus on clearing all of the Doom Challenges. So far it does not feel overly challenging. We are discovering though, that it is a very fast and easy way to build both money and experience for our new Skylanders. Watch as Conner and I play the Kaos Doom Challenge (Waves 11-20) in the Horrible Something Temple and see how we gain several levels for a couple of our newer Skylanders.
