You need the crown nintendo online for snow lands because then 4 players can catch the legis, because it is difficult alone, or you can catch the legis alone, I mean you pay for the DLC and it would be a shame if you still had it nintendo Online needs because it alone is difficult to catch legis in the raid.
You need Raids Online if you do it with other players, but you can also do it alone with NPCs as allies. Just as it is in the main game. The second DLC has not yet been released.
You don't need online unless you want to do other raids online.
The online subscription is only used for multiplayer activities, not when you play alone.
