I boost auras with monk guardian on to the buff beam. I use 2 summoners with huntress and monk guardian pets.
Hint 1 I found placing the seed bomb tower on the beam and as far south it doesnt get hit by ogres as much
Hint 2 try to place everything as far away from the core so ogres dont hit it after swinging
Hint 3 place orcs and mages if things get too heated at the stack
Hint 4 Make sure your auras cover this path at least a little
The stats are mine at the moment but started running this map below 5k
Ofcourse tweak the buiild to your liking if you feel like it.
