Mirror Images/Black Mage


 * Black Mage: WHM subjob, 5-6 Yagudo Drinks, 1 Fish Mithkabob, Musketeer Pole as weapon, Life Belt, Eremites+1, NPC set to Stalwart Shield, ethers/muslums. You will mostly be trying to heal your NPC just like white mage.  When you approach Vassago cast Stun.  Vassago's Drain must also be stunned.  Make sure to keep up elemental debuffs (especially Drown) and cast Fire II as it is readied.  Keep in mind most of your mp will be used to keeping your NPC healed.  Keep all debuffs up.
