When I 1st tried I kept dying for about an hour before giving up and then doing some leveling. When I finally defeated him I used Noel as a fulltime SEN. The only monster I used was Chichu. Sarah alternated between all roles. This isn't the best strategy, but it's how I first defeated him. --- There can be only one.
Try and use Tortoise formation (SEN, SEN, SEN) when they perform that triple mega flare attack. It will greatly reduce the damage dealt to all your party members. --- Gen IV FC: 2536-3829-5092 Gen V FC: 0819-4243-0361 PSN: blueink8
