Strategy

To vanquish the hordes of Unversed that populate this battle, make sure to equip crowd-control Commands like Mega Flare, Quake, Magnega or Faith.

Iron Imprisoner III

As always, you will have to rely on a projectile Shotlock, like Bio Barrage, to make it through this round, and you must have at least one Curaga in your deck. It is also a good idea to equip Vanish, to give yourself more breathing room, and Firaga, to deal extra damage while your Shotlock is charging.

During his hammer spin mode, it is wise to keep dodging due to his increased movement speed as his HP dwindles. Any three-tier Command Style will always work due to the finishers. Another method to charge the Shotlock is to equip the Damage Syphon, Once More and Second Chance abilities to absorb and withstand the damage taken.

As his HP dwindles, It is mandatory to block when he unleashes his true strength.

During his Explosion phase, it is wise to stand further from the boss to avoid being sucked in. If the protagonist is caught, do not worry as it is mandatory to block his explosion.

During his Possession phase, It is wise to keep running and dodging to avoid the flying tiles. Do this until the end of the phase.
