Kaeko's insight is correct here, and this is true not just for manaburn parties, but for groups of a more traditional setup. The critical period for this fight is when Garuda is about to trigger her Aerial Blast stage, and groups that don't put much thought into timing here won't be as successful.

Gear is certainly important for this encounter, but our mastery of this instance was the result of countless hours of learning the fight with most every reasonable setup imaginable.

Many thanks to all our Legacy members for pushing it to the limit here. Very proud :3
