Success! Concept is to pull all the mobs into one area. It kind of works (we won the map), but is a little slow. waves 32-35 was 20 mins combat time. I don't recommend starting at 22, because the golden heroes stop coming on wave 23, so start there if you're going for armor. I haven't tested it on Rtuhless yet, but worked on NM.
Party: 1 TB Monk, 3 summoners with huntress/monk pets
