=== Tips on the battle ===
Once his HP drops below 50%, he will use a more powerful version of the warrior skill "Defensive Formation" increasing his physical defense by 70%, but decreasing his physical attack by 70% for 30 seconds. Magical DPS should watch out to avoid taking aggro from the tank, since he will do less damage on the boss for that period.
Once his HP drops below 20%, he will use a more powerful version of the warrior skill "Berserk", increasing his physical attack by 90%, but decreasing his physical defense by 90% for 30 seconds. This will be the final test this boss will give you, you should keep all bursts that increases defense, reduces damage or attack of the boss, reduces damage taken, increases the total HP or increases healing power, as the tank will be easier to kill at that point. Also, magical DPS could keep their bursts for this phase, as the lack of physical defense will allow the tank to deal higher damage to the boss, increasing his threat.
