Thread: Challenge Quest help plz

Alright, so I'm stuck on solitary battle 3 right now, I can't even clear it 1 star. Any of my melee units are all too horrible to kill them all fast enough, so I'm wondering what unit I would need to focus on powering up in order to clear the map.

Basically, all my power is frontloaded onto Bashira, with my team looking like:

Aside from this, I'm currently farming Commision Sorties on Return to Ruins for resources. I'm currently level 45.
Any melee unit I should be focusing on obtaining and/or upgrading?
