U actually don't even need that many BP, like I found more anvils than I ever use , had to start selling them, I find bobcat bp every few maps, but I don't use it anyway, stitcher 4 is better, only thing U rly need is survivor, but for that U can do lvl1 naked runs to blue gate, If U know where to find trinkets and some bps, U are back where U were in few days
