This build has been tested with 5k main stat heroes. It is made to be as safe as possible especially when your tower boost goes down.

Build Note 1: I did not find that I needed minions with this setup and a properly managed Tower Boost. Add minions if you struggle.
Build Note 2: The refelct beams are there to protect your towers and Tower Boost Monk from spiders. Getting webbed and not paying attention is the reason for most of my failed runs.

Waves 22-29 Note: I stop tower boost at mob count 1100 and then start the tower boost after cool down to handle the final Genie/Sharken rush.
Waves 30-35 Note: I stop tower boost at mob count 1600 and then start the tower boost after cool down to handle the final Genie/Sharken rush.
Wave Note: I used a tower boost monk, two Summoners with Apprentice and Huntress Guardians, and the builder Warden.

Hint 3: I put my builder Warden on top of a bookshelf at hint 3. I was able to make it through all waves without dying.
Hint 4: My Tower Boost Monk stood on the Warden towers and shot at hint 4.
