There are more builders on the field than I want, but this is the fastest and most secure build I could come up with at this time. It's faster to set up than it looks like once you get the rhythm down. My builder order is Huntress, EV, Monk, Warden, and then Hermit.
Place Summoners (with apprentice/huntress guardian pets combo) on the Hint 1 through 4 tower stacks.
The Forest Golems are placed on the end of the buff beams. Hint 1 and 3 tower stacks are built between the Forest Golems and their neighboring tower stacks of Hints 2 and 4.
Hint 5 auras have the Ensnare aura as much south as possible (at the bottom of the stair thing, in front of the chest), and the Strength Drain aura is right behind the crystal. The map planner does not allow me to place the auras any lower.
Upgrade the traps buff beam during the wave.
