I've never tried this but I believe if you had a BRD and MCH in party, using Battle Voice and Hypercharged MP restorations, you could infinitely Flare. It sounds sick on paper until you realize you're missing out on BV Foe's and Hypercharged 5% buff, and DPS losses from the BRD and MCH, to do so, but still an interesting concept.
