Hey weskey, depending on what gamemode youre playing here's a small rundown;
For survival i'd recommend learning some more about the 'logging' job and create a wood farm. Wood sells for a lot if sold in large quantities. IF you don't have many resources at your disposal, a simple cactus farm could work too for instance. Also make sure to check out the dojo, farming here is also pretty beneficial. I'd check out the /shop and their sell prices for crops.
For skyblock i'd recommend leveling up your island and going to the pharaohs realm. In here, you'll be able to get your own personal milestones up and unlock better rewards & more money. Check out the /shop and its dynamic economy. Some crops are doing better now, whereas in a couple of days that might be completely different.
Factions on the other hand mainly uses cactus farms for igm income.
For lifesteal i'd recommend checking out the colloseum. For farms anything could do, but you'd gain the most igm from colloseum imo.
Lastly on prison, farming is nerfed here pretty bad. If you wanna get igm, you better resort to mining.
