not any real good money making if ur not making AD's fcp's slims or mvping but...
u can train ur pet on mushroom spores or mob and cart revo them to get karvos and spores
then use those spores to plant mustrooms and then collect red bloods, crystal blue's, and even more karvo.
If u have a sinx make those into edps. and REPEAT!
This is what the people do that you see vending like 800 red bloods 800 crystal blues and 200 karvos.
