Mixing high adrenaline gaining skills with "Save Yourselves!" can reduce damage by 87.5% (Wiki checked) through the +100 Armour bonus.
Maintain Agressive Refrain and at the start of the battle, use both Focused Anger and FGJ, when FA runs out FGJ will've recharged allowing another use and maintaining the adrenaline gain bonus. Spam both Wild Throw and Save Yourselves using "There's Nothing to Fear!" frequently to assist the monks. Leader's Comfort as a self heal, you should be fine.
Armour's simple, high health and Leadership. A good Luxon Rank is great meaning less downtime for Save Yourselves. AI target those with the lowest armour so be wary of accidentally tanking when Save Yourselves is active on the other party members. Energy isn't really needed, the base is fine.
