Build:

• Build under the bridge on the west side - opposite of the chest
• Build auras, buff beam and 2 Deadly Strike Towers during build phase
  • You cannot build as much without doing the secret, should still be doable

Waves:

• First Wave: Apprentice Builder + Upgrader
  • Drop mana with the Upgrader to the Apprentice ASAP then start upgrading leaving it on auto-shoot.
  • Finish the build with the Apprentice ASAP.
• Second wave onwards: TB + Summoner with Huntress and Monk Guardians.
• Boss wave: TB + HB Monk with Eye of Devastation pet + ? + ?
  • During boss fight:
    • Keep all heroes under the bridge.
    • Use HB with monk and let it kill the boss(es) with the Eye of Devastation.
    • Consider equipping a cat on one of the two other heroes to increase Monk's damage.
    • Consider dropping mana with the TB to delay HB cooldown (N drops half the mana you are currently holding).

There may be better builds now that use Warden.
