So, this will be an odd request, but according to Pathos on Discord, it's totally possible. (Even if you have to have it replace what artifact digs up) Can anyone make/know of a mod that exists that makes it so every artifact you dig up you've already found increases the chance of finding one you haven't found yet? Say for instance you have a 5% chance to find an artifact you don't already have. Then if you dig up one you already have, it bumps up to 6%, until you eventually get one you haven't found already, then the chance resets.
