This is a mod where you can take the lunch money from mobs in the game.
It will work for any mob even from other mods. Simply you hit them and they lose some gold nuggets. When they die they lose more gold. Simple enough right?
PS - If I need to balance it a bit more just let me know since it felt a bit OP for it to be easy to get gold but gold doesn't do much for you in vanilla.
