Finally beat the event.

Took blm, rydia, cloud, tyro, and wakka to both hundred and heli gunner. Blm died on the first and second rounds accordingly, but with rydia/thundara, and tyro with wakka boosting a thunder strike they barely went down.

Rufus I took tifa instead of blm. With wakka boosting cloud I took out puppy without any trouble. Rufus killed rydia, but for a couple turns I was doing at least 2k till tifa died then went auto till I got Sephy!
