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.
Bomb x10
Locke’s Lost Chapter: “Treasure Hunting” Pt. 10 (Normal difficulty) has 5 Bombs in 3 waves, completing the mission in 2 fights.
Note: The Bombs from Palom’s Lost Chapter are easier to reach, but they do NOT count for this mission (probably because they use a different model with scribbled-on faces, and the ID for that model is not listed as a Bomb in the game files. This mission requires “Bombs”, not “Bomb Types“)
Tyrant x20
Story Act 2 Chapter 9: The Destroyed Square Pt. 2 (Normal difficulty) has 1 Tyrant in 2 waves, completing the mission in 20 fights… but you might as well just wait and get it done while farming the upcoming Raid!
