Crown Tundra: How to get Regeleki or Regidrago
There's a plethora of mysteries in the Crown Tundra to be solved, and then there are even more mysteries once they have been solved! A few of these are pretty well hidden, such as how to get Spiritomb; who would have thought by interacting with a random tombstone would trigger a riddle. Another family of riddles is acquired in 4 different ancient tombs across the icy region, and in each one of these puzzles, there is a Regi-Legendary Pokémon to be captured!
