Build first auras, buff beams, reflect beams (only those on Hint 4, you'll build the others next wave), wardens towers and the dsts facing south.
During first wave mana drop so you can place all the rest of app towers. I use TB monk to drop and I also put a dps monk with a wizzard pet on south core (dunno if it's rly needed).
For last wave, bring a dps huntress (better with forest / frost rifle), TB monk, HB monk and guardian summ (huntress + app).
For boss fight, stand on Hint 3 with huntress + HB. I first focus the boss spawning east (Hint 5).
