Malacore actually surprised me with Cursed Elegy skill (10 MP) casually dealing 37k damage at level <70. (From Ultima weapon)
I dressed him with Genji set to boost his Magic and Bone belt to boost Vigor.
Joining the team late but worth grooming, I think.
I love Brindle who casually deals 40k damage per turn with normal attacks with Crit build, too. :)
Mog... I don't know what to do with him. lol I don't like rotating skills ^^"
Bosch is your main healer, I think. Though his healing is unpredictable ^^"
