Another thing ofc is if ur squads are dying before the end then u'll get less money (dunno out of my head if the bosses drop a significant amount of gold). But I'd just compare if the money u get after 12-5 is then still more than 12-3 or not

I don't have squads die until the boss normally. I do pretty good getting the chests, but sometimes we don't get all the pests (thanks to rng).

Also, I leave everyone at the starting positions (sometimes switching squads around due to speed), is there a better way to approach 12-5?
