And energy sheathe isn't an option because imo this Dragon fight is quite easy. The hard one is the well - energy dragon. Thus I often do have energy sheathe twisted it, but it's the electrical version to aid in battling the blue dragon, which will have no effect on the white dragon.
Also just did this on my sorc.. Rediculously easy compared to melee, got lucky on my shiradis buff, so had the uber buff and burned him down in 30 seconds, taking only a single hit (no exploits used, just lots of wind dance). Actaully killed him too fast and had to do it twice, still had 1500+ sp left..
They really should of improved dragon AI to be able to hit ranged characters, especially ones that devastate meleee so heavily like white with its annoying aura.
