Freddie's Corpse: This one is built into the game, no need to edit/install files. Find the body on the south edge of the Weirdwood map near the spider caves entrance, it has a key that unlocks the small building next to the guards tower. Inside are chests, one has cash and the rest have potions; (most of) the potions can be sold, too. Some potion chests are empty until you complete certain quests. The chests refill every morning, you can loot them daily. There's also an item on a shelf that makes the MC waaaaay overpowered if it is equipped in the MC's necklace slot.Any way to cheat money here?
Save File: If you just want a pile of cash and not mess with other stuff, there's a Day 1 Hour 16 save on the discord which has a stupid amount of coins but no quests or other actions done yet. Using other people's saves can be risky but this one is known to be safe. (You can change the MC's name on it to whatever you want by using the book on the Mayor's desk).
Ears Grinding: You could also grind goblin ears using scumsave (~16k coins/day if that's all you do), but that takes a lot of IRL time and depends on not knocking up Shakala.
