Birthday character?

Pros: ・Healing skills are stronger compared to others. ・The illustrations are cute. Cons: ・Skill performance is the same. ・If it's not your favorite character, there's no benefit to owning multiple of the same character.

I see. Thank you.

For collecting Amatsuyu on your birthday, it's better to have them ready. If using them in a formation, I use them in a formation for leader count. I farm leader counts in the 'Solitary Envy' (nicknamed 🦐) on the Easy difficulty live by myself. At that time, if you have 3 birthday cards with high recovery in your formation, you can clear it just by hitting the long notes.

I see.
