Strategy
A party of physical attackers is required, as all damage Quetzalcoatl takes from magic and ninjutsu attacks is reduced to 1/3.

Almost all of Quetzalcoatl's attacks are lightning-elemental, except for its party-wide Aero spell, the non-elemental physical attack Body Slam and the gravity-elemental Tornado. Aero is only used in the first phase, so it should be ignored if possible.

Bring potent healing Soul Breaks, as almost all of Quetzalcoatl's attacks hit the entire party, and Savage Thunder Call in particular lowers their lightning resistance.

Savage Thundaja's Paralysis can only be blocked with a status barrier from such Soul Breaks as Tyro's Arbiter's Apocrypha. If not, time Ultra Cure to get the affected character back online.

Finally, Quetzalcoatl's Lightning Rage will reduce all damage it takes by 50%. To break it, bring a character with earth-elemental Overstrike Soul Breaks or the Heavy Physical Stone Press ability.
