SCH keep up with windstorm + Hailstorm and nuke. Should switch between Windstorm and Hailstorm each time when it's in the Air.
COR/WHM
The premise of the strategy is to keep Ouryu asleep while he is on the ground, and nuke him hard while he is in the air.
BLM should focus on keeping Ouryu slept while on the ground (Don't try to sleep it w/o Elemental Seal), and nuking with either ice or wind based magic while he's in the air.
BRD should try to land an Ice or Wind Threnody on Ouryu to increase the damage done by the BLM. WHM should keep applicable bar spells on the PLDs as much as possible
PLDs should build as much hate as you can while Ouryu is on the ground while he's been slept, and cure other PLD who has the hate to banlance the hate.
Let's get this done and make some Cash for the bank!!!!!!!!!!!!!!!!!!!!!!!!!!!
