WAR/NIN This battle wasn't too bad. My NPC was set to "Healer" type and was equipped with a shield and axe. At the start of battle, I used a Sole Sushi and Utsusemi. I ran in, provoked Vassago, and that was pretty much it. Shadows took care of Vassago's attacks, and when he readied Blighted Gloom, I unlocked and ran into the tunnel. I hit Mighty Strikes with about 30% of Vassago's health left. That wasn't enough to kill him, but me and my NPC were able to do a Fusion SC in that time, and after Mighty Strikes wore off, it only took three more hits to finish the battle.
