Tested 1 time, worked, was about 13 mins combat time, and overall 23 mins. Very safe. If looking to speed it up, can cut the slow auras. I am more for "safe" than fast on these though.
Goal is quick and tower kill, and safe build. Leveraging aura power here for the normal mobs and then wisp for boss??? 18 towers used up north for max boost-ability.
9 Reflects used around the stack.
Party: 1 TB monk, 3 summoners with hunt/monk pets
Just start with splits in, build all auras and buff beams 1st wave and south golem.
2nd wave, build the rest
Rest of the waves, upgrade and boost.
I have 2 Aura monks, one for dmg auras and one for slow/weakness
So far, it's been unreliable, the reflect beams and the postioning of the summoners seems to be the critical factor. Kind of want to keep summoners a short distance from the towers, so they don't both get hit when a shot comes through.
