Place both strength drains, buff beam, both mortar and harpoons during first build phase
During the wave i have a Tower booster on alt and Apprentice builder on main. I drop the Apprentice mana during the wave to place the dsts and lts.
Past that just have Tower booster and Ini booster till final wave. On final wave i do 2 monk and 2 squires. The squire builder and a random squire with a Destructive polybius pet on.
You can without a doubt do this with much lower stats.
