* Stats are just my stat range, probably can get this done with around 4.5-5k. Bosses will take a while though. BUT this can tower kill if you keep the snowman far enough away.
Build Phase: run around with aura monk placing aura stacks as you are collecting mana. Place BBs (both 4DU) and all 5 cloud towers. Take out owl Guaridan for wave, and drop her mana.
Wave 1: Build all owls (10) durring wave, up the BB if you can get enough mana for it (south core should be fine).
Build Phase 2: add pylon, and stack the spore shroom/wisp on owls. (Reflect completely optional, but can help with snowmen if you struggle)
*** Just grab secret whenever you can, Usually I fly over and use a fully RESed summoner durring wave 10. ***
*** Variation ***
Drop one owl for a wisp on the southern BB if you are having trouble with the ogres down there, they tend to come in pairs in the last 3 waves.
