The navigation bar is all you need to get started. From there, you can go to Teams → select any team listed.
Each team page displays its most commonly used lineup, a choice section on the right, and bench options for alternate characters.
To view a character’s equipment setup, simply click on them in the choice sections. On Mobile, you need to scroll to the right to see this section.
The first equip from the left in Section will usually be your must have equip. Any equip in the extra options for section 1 will usually be a replacement for the right most equip.
The Extra / Notes section shows alternative equipment options depending on specific character pairings within your team.
That’s it — hope you find this helpful and have fun!
