This map has 140 DU, not 90 as listed in DDPlanner.

Build:

• Build everything except the Forest Golem on in the south stack and however many Lightning Towers you can't build.
  • Apprentice builder stays in combat wave to finish building
• Note: 3 DU left. I'm not sure what to do with them so I usually put 3 more Reflects near the mid core for boss fight.
• Deadly Strike Towers = yellow arrows
• Seed Bombs = green arrows

Waves:

• First wave: Apprentice Builder + Upgrader
  • Have Upgrader drop mana to Apprentice Builder and start upgrading ASAP
  • Finish Apprentice Towers ASAP
  • Towards the mid/end of the wave you might need to go to the South core with apprentice and do a Purity Bomb to kill trash mobs there
• Second wave:
  • Build the second Golem
  • TB + Upgrader if need to keep upgrading
    • TB + Summoner with Huntress and Monk Guardians otherwise
    • TB stands on marker 3 and shoots against the wall as shown by the black arrow (assumes you have Madness Boulder Thrower)
• Other waves until Boss wave: TB + Summoner with Huntress and Monk Guardians
• Boss wave: TB + HB Monk + Ranged DPS + Ranged DPS
  • I like to start boss fight at marker 4 with Huntress and shoot east.
    • One of the bosses spawns east from there, the other south in the center of hte map

Not too happy with this build but could not find better one yet.
