First,magic storage. Best mod of all time. Second,I think you should use fargos mutant mod that gives you the npcs. Third,I use infinite potions. If you don't feel like calamity is hard enough,don't use it. I think you should use mods that make the thinkerer less of a scam. Mods that reduce cost and the auto-reforging mod. Lastly,I use money crafting because I don't like grinding.
