Wave 1: auras, traps (can do 4 instead of 3), buff beam, forest golem. if struggling, dump an orc somewhere in the middle to distract ogr. Dps down ogres, i used nosferatu.
Wave 2: move your gas trap in range of your buff beam via jster then place it roughly in the middle  bottom beneath crystal. Place down the nature pylon, and all warden towers.

Wave any not final: place down minions and upgrade on an adept. Ideally, have a booster summoner out with a huntress + monk guardian during this.

1: On the lil penis pylon thing that looks like the thing u use to skip countdown in bossrush, place all ur shit there. during boss, sit on top of stack of towers on top of penis pillar thing. 

2: Create a great wall of minions, very tight wall. should me a nearly complete circle of em. probably best with orcs but definetly dump some spiders in there too.

4: Summoner with monk guardian, huntress guardian. Any extra summs should have a combined 1 app guardian, then probably a fuckton of squire guardians or something it doesnt really matter. 

You can target-farm 3 weapons with this, but it will take forever. personally, I recommend 2 monks on final wave for 24/7 tb but not needed (I did with 1).
