Build Description
Build hint 1 on edge of building, upgrade north and south buff beams once before starting.
Build everything except hint 2.
Build hint 2 during first wave with upper on split dropping mana, then upgrade buff beam to 1 star and go to hint 1 and upgrade.
Run upper only or upper and warden for waves until last wave.
Add dps and tanks for boss wave, dodge the boss attacks with huntress and hero boost her with cupid monk (hint 5) away from tanks.
Keep all characters away from towers during the boss, tanks I am using are fairy/cupid hermits to soak damage and drop shields.
