Celestial Star deals many hits and adds a lot of energy to the Gauge. Due to this fact, and even though it deals a lot of damage, it is best used third in a PWS sequence, allowing a fourth PWS to trigger and helping to maximize its damage. In most cases, Celestial Star and Meteor Swarm are the strongest PWS in the main game due to their high modifiers, the high MAG of staves, and the fact that most enemies have lower RST (resistance) than RDM (reduce physical damage).
