Jinx will be the only unlocked champion when you first play The Path of Champions, but you can unlock the rest using Champion Fragments.
To unlock a champion:
- Select the champion you want to unlock from the Roster.
- Click Unlock under the Champion Card.
- You'll need 30 of the chosen champion's Fragments to unlock them. If you have enough, click the button showing the Fragment amount and voilà! The champion is yours. Don't have enough Fragments? You can earn more through quests, Champion Campaigns, and World Adventures!
Once unlocked, you can start that champion's Campaign or use them in World Adventures.
