Infinite Dungeon levels now can have challenges. Each level after the second will have 30% + level chances of having one. Challenges can be a range of different things that you have to do on this level. If you manage to do them you get a random reward, which can be a randart, stats/class/generic/category or even prodigy points and perhaps more!
