Build Description
You can lose if spiders web your units, Sharken push a wall, or Djinn eat a buff beam. The reflect beams are everywhere because of Spiders. There are 10 Archers in the bottom stack and 3 Lightning Towers on the each stack. The south and SE auras and traps should be touching the buff beam. Upgrade the buff beams before the first wave. Make sure no Lightning Towers or Physical Beams die.
Hint 1 Boost Monk position.
Hint 2 Ogre Copter drop locations. Lightning immune Copter Ogres can land at the north location if your Lightning Towers are on cooldown. These can't damage the Crystal, so it isn't an instant loss if it happens.
Hint 3 Djinn attack locations.
Hint 4 Stack Lightning Towers (hotkey + spacebar simultaneously).
