Choose the route that serves your goal
| Your goal | Route |
|---|---|
| A locked monster for tonight’s local match | Tournament Mode, then Custom Battle |
| A locked monster in Adventure | Complete its normal Lab progression |
| More research progress | Normal eligible play with Tournament Mode off |
| Friends on another system | Check the multiplayer and platform conditions first |
The visible Custom selection is the success check for the party setup. A selectable monster there does not establish a permanent unlock for Adventure. Follow the persistent unlock route.
