This build is extremely consistent even after 2000 enemies when a lot of mobs spawn. My goal is to maintain golden enemies all the time, so I put 1 TB and 3 Jester Wheelers positioned behind the Mortars. The Jesters must have Hunters / Hunters / App Guardian to be truly effective while the enemies are golden.
Two more things: for people with low stats, there are limitations. I'll try to make the stat breakdown clearer regarding what you can or cannot do according to your average stats, and also remember to check if you can handle passing 2,000 enemies while doing the wheel—if you can, enjoy!
