Disclaimer - this probably works with lower stats. I just haven't tried it with them.

Start on 32 and build next to the forge. The LTs and MMTs should be on top of the crystal cluster there, while the Hermit defenses should be in front of them. Black arrows indicate the directions of the Magic Missiles.

In every wave, use a Tower Booster (I use 7400, but lower should be fine) an afk Apprentice with a Huntress Guardian and your builder apprentice as an AFK hero

For wave 32, bring an Adept upgrader to get the stacks upgraded. The upper should shoot down the North West path while the Tb should shoot down the South West path

For waves 33 and 34, bring a wheeler. Kill % and Dmg all are your friends

For wave 35, bring DPS App or Purity Bomber.
