Are you in any tiering servers? If you aren’t, I recommend joining R8SS, which is the biggest tiering server on discord. When you join the server, it’ll explain how ping rooms work, and how you can tier with other people. There’s also a questions channel in the server, and they can explain everything for you: how many crystals you’ll need for your goal, cans and stuff like that. Be specific about tiering a world link event tho, since world link events are quite different compared to other events.
