Got Zeus. 13 stones. Not bad, could have shaved four off that, but made mistakes. Died first round by missing my AOE orb and only hitting one monster. Dropped out and used a stone for stamina. Second try, I couldn't get rid of the light mask fast enough, so one stone there. Spent another on the demons due to a sloppy match and not hitting them hard enough since I was trying to save a few orbs for the chimeras. Got to the chimeras with no dark orbs, so I used both vamp and CDK skills at once. Should have used them in separate turns, would have given me an extra turn of good damage when I had a ton of heart orbs drop. So another stone. Thankfully their turns were synced, which is probably what kept me under 20 stones. Zeus wasn't too bad, but some extra levels on my team would have really helped when I was pecking away at his remaining life.
Still, happy I ran it. Now, what am I going to feed this guy...
