How do I find the map pieces to get into Omen Islands?

You need all 9 of the Uncharted Land Map pieces

Here's a list - https://www.subetalodge.org/list_all/search/uncharted+land+map/mode/name

You can sometimes get them in random events, or you can just buy them from other users. They're not super expensive.

Once you have the pieces in your inventory, take them to the Treasure Maps link from the games page to turn them in. :)

Thank you :)!
