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.
Greeden Types x20
Story Act 2, Chapter 8: 8-13 Fangs in the Sand (Normal difficulty) has 1 Greeden in 4 waves, completing the mission in 20 fights.
You could also just wait for Guy’s Event, which will surely feature a good amount of these foes.
Necromancer x10
Ciaran’s Lost Chapter: Caravan of Hope Pt. 8 (Normal difficulty) has 3 Necromancers in 4 waves, completing the mission in 4 fights.
Story Act 2 Finale, Part 2: 12-1 The Final Battlefield Pt. 1 (Normal difficulty) has 4 Necromancers in 3 waves, completing the mission in 3 fights.
Diabolos Types x15
Pick your Diabolos Flavor: You can easily farm this on the still ongoing Divine Diabolos co-op, or do it without any extra effort if you are still farming the Divine Summon Board… if you’re finished with both, you can also get it while farming Wild Points for his old summon board.
