Buildpase 1: Build all aura's, the gas trap south, buth EV buffs + 3x 1du reflects around the towerbuff in the back and 2x 1du reflects in front of the southern (minion) buffbeam. Use the remaining mana to build 1x spider, 1x mage and fill the beam up with archers. I leave it like that until the end. You can add more or different minions. 

Combat wave 1: During the wave upgrade the buffs and at the end of the wave move to the south and preferably max out everything there. Save at least a full inventory of mana for the towers.

Buildphase: Build 4du presents facing the minion wall. That's all 72 du not in the planner, so 18 presents you want to convert in either LT's.DST's or harpoons. During combat use a upgrade jester and tower move the bowling ball towers and slicerdicers out and sell them (NOT while on the buffbveam or you will loose it!!).  

Repeat next buildphase until you fill out all du or get close to that. With 16 left I often build 2 dst or with 12 left 2 harpoons. 

You can get unlucky, but the only times I lost was when I got no LT's in the first stack, which is very rare. 

On the bossfight bring out your tower booster, 2 summoners with app+huntress guardians and your jester builder. With max resists inside your healing aura and tower boosting should keep you healthy enough. High stats is real fast boss clear times (like 10s if he doesn't beeline south outside harpoon range).

Lower stat options:

Hint 1: For safety you can enclose the sides with more minions. 

Hint 2: Add a buffbeam boosting the aura's. Might increase clearing times with mobs stuck in the gas trap if you buff that as well.

Bossfight: Move behind the minion reflects if need be. Lower stats will take longer ofc, edpecially when the boss moves south. As long as you're tower boosting the build should easily hold. Even when TB goes down you can hold if you manually repair targeted reflects. Tried that in my test runs. 

Stats included are the ones from my testrun, forgot to strip my ev more :P Might try a couple more runs later on.
