You have no need to cheat. Just do the runner farming. It's not worth cheating if it's your first time through. This game isn't supposed to be easy with buying stuff. You should never have to pay for potions now since you have the tower, just find more formulas to add to your list. And check for any dups you have for potion and enchantment formulas. They will be in your battle chest if you ahven't moved out of your inventory. You can sell those for cash.
