Build Description
Boss kept killing towers so I decided to use traps. It's slow and you kinda have to clear waves yourself on the east/west wings but cores never take damage and worked first try.
You will need a TB monk and a dps during the waves and boss. (I used my squire)
Wave 1 - Setup traps, auras, buff beams.
Wave 2 reflects and golems.
My huntress trap stats are just under 7k, but probably could do this with lower stats.
