You need main split as app, second split as tower boost, third and fourth split must be summoners with one huntress guardian pet each and one monk guardian pet each standing at the main stack.
This build works for shark and axolotl farming the best and needs no other maintenance during combat. However if you are running duck farming you need to upgrade everything.
This build is alt friendly and can be done with lower stats if you upgrade the golems during first build phase.
Sharks are wave 23-25, axolotls are 28-30 and ducks are 32-35.
