I haven't been able to beat Maxwell yet, so others can probably give better advice.

Narza gets Sinister Orb because you need him to use his mitigation BB almost every turn.

Rowgen gets Divine Stone because once he fills his SBB guage, it auto-refills. Rowgen also gets Omni Gizmo for increased BC drop.

Grahdens gets Medulla for increased attack and defense against Maxwell's light element.

Zelnite gets Mystic Lantern, because it is your next best stat boost.

Altri gets Sacred Jewel because it is your next best stat boost. Altri also gets Refined Gem so he can't be paralyzed or cursed, then he can use his BB/SBB to cure/negate everyone's status ailments. (Helps with Juggernaut and Abbadon, but Maxwell inflicts only weakness and injury.)

--  In general, I prefer stat boost that always happens (Medulla, Sacred Jewel, etc) over "chance" spheres (Soul Spear, Magical Axe, etc). Murumasa is not helpful here because it only works for the first two turns and this will be a long battle.
