Darker Side Dupes

From SMO.wiki

Darker Side Dupes is a speedrun category on the Category Extensions board for Super Mario Odyssey. This category consists of collecting 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. Timing begins when selecting "Start" on a new file and ends when grabbing the Multimoon at the end of the Darker Side Kingdom.

Route

Roughly the same as Darker Side, but some moons are routed out for duplicates.
