Tip: Make a party with two of the required summon/characters + a fast group damage dealer and you can clear the character usage missions while also farming the required monsters.
Minotaur types x15
The Brothers (Divine) is the current co-op event, and what a coincidence, it features Minotaurs! Farm them with no effort.
Death Machines x10
Zack’s Lost Chapter: Shining In, Someday Pt. 7 (Normal difficulty) has 5 Death Machines in 3 waves, completing the mission in 2 fights.
