Build Description
Setup auras, buff beams, reflects and the pylon then the rest lightning towers.
wave 2 delete the LTs and restack all towers to finish build. (blue arrows are deadly striker tower directions and the blue bar is the cutoff for the south/east directions angles.)
I used 2 summoners with guardian pets of your choice and a TB with a jester wheeler.
Hint 2 is where I stood with my monk TB and the direction of my shots. (black arrow)
The minions are optional if your stats are high enough, but I went ahead and found a good way to place them for fail safe.
