I am loving this first new dungeon. It drops starter dragons, it drops healer girls, it drops mystic knights, and it drops dragons. I've gotten a lot, and it's not even at an increased drop rate.
Also, they drop lvl 10 fodder monsters. Sweet. :3
I can't wait to go through the other dungeons as well.
Edit: I just wish Ripper Dragons wouldn't change their Actives with every evo they have. Srz, it makes a pain skilling them up.
