Recommend starting at 28, running to 40. Pets are strong/desireable, kill rate is ok, Acc are good. This has great prizes, though the armor farmability is slightly less than great.
Optimized for the 12 tower build, to allow a roamer/extra
Hint 2 is on top of that rock right there (for height boost)
Party: 1 TB Monk, 2 summoners (huntress/monk pets) @ hint 1 and hint 2, 1 extra of your choice (builder squire maybe?)
I have squire builder in standing on the rafters by the forge looking at the ceiling for better speeds.
