I'm constantly cooking and testing so expect changes, but this is what I've been using for a few days.
Do the secret before doing this. Please please please please please please. The 14 du is worth it for any TW build. https://www.youtube.com/watch?v=3Of4Iw-7riM
The north auras are at the top of the conveyer belt ramp.
Wave 22 - Upper adept, TB (Stands on Hint 3 / 1.5 "Grates" in the tunnel, shooting towards Hint 1. pretty much just make sure it hits both stacks), 2x huntress summoner on Hint 1, any character with a huntress guardian on hint 2 (I do gw for the Nessie Launcher :3). 
Waves 23-35 (When everything is upgraded) - Replace Adept for Warden builder.
Sometimes you need to repair south auras. Alternatively, if kobolds here are giving you issues, replace 1 shroom pit with a buff beam (Hint 4). This also lets TB hit the south auras to heal them. This is safer but slower.
Stuck djinns suck, but there isnt that much you can do about them sadly. Even with that, at my stats (8k/4.5k/4.5k Warden, I sometimes do 7k/4k/4k when I forget to swap aprentice armor back), I'm getting 34 minute combat time.
In terms of armor, you're trading the ability to wheel for golden enemies on Royal Gardens for actual drops outside of armor. Take your pick.
