Darker Side Dupes
Darker Side Dupes is a category on the Category Extensions board for Super Mario Odyssey. This category consists of getting 500 moons to access the Darker Side Kingdom and getting the Multi Moon at the end of it as fast as possible. The difference between this category and Darker Side is that you can buy duplicate shop moons.
Route
Roughly the same as Darker Side, but some moons are routed out for duplicates.
