Fina is one of the main characters who will join your party in Final Fantasy Brave Exvius. To get her, you simply have to keep doing the main story missions. Once you get to the second island, Lanzelt, continue following the string of missions until you clear the Lechios Hills partway through the island. After completing Lechios Hills, Fina will automatically join your party, and you’ll be able to level her up like your other characters.
Fina is a White Mage, so she’ll be equipped with all the usual spells like Cure, Shell, and Protect. She’ll be able to use Cura and Curaga once she hits level 28 and 44 respectively as well. Aside from that, she’s also got spells like Prayer and Cheer, which can buff your party’s attack and defense. Her Limit Burst, Holy Ray, will deal a large amount of magic damage to a single enemy, so she’s really only good for offensive purposes when you have it charged up.
That said, she is also one of the more competent healers you’ll find in Brave Exvius, so I’d highly recommend keeping her in your party and leveling her up once she joins you.
Final Fantasy Brave Exvius is now available on iOS and Android devices.
