Here's a video of my OTKO on the Eternal Summit Bahamut Esper Battle.
=Team Setup=
Soleil - Buff MAG
Delita - Break SPR
Olives - The only way I could reliably chain 30+ with Mirage from the Pod 153 TMR was with duplicate Olives. Could be replaced with any other units that can perfect chain.
Zyrus - 860+ MAG, dual Draco Spikes, maxed out Limit Burst for all the damages
Onion Knight - Friend with Bahamut summon (Megaflare)
Once I knew what to do, it was easy. Buff MAG, break SPR, start Bahamut summon, then initiate Zyrus' LB immediately followed by the Mirage chain, which Zyrus' LB capped. One shot. Boom!
