This guide will tell you how to beat the hardest boss in the game in 4 turns or less.

The Boss may not follow the order given, but I find that this is what he does the majority of the time.*

First off, you need to have all 4 immortals in your party and have them at least lv 70 or higher. Then pick a mortal(preferably Sed) to be the 5th member.

Have your immortals have a skill set with these skills in it:
Reduce Casting Time 1
Reduce Casting Time 2
Spirit Magic Lv 8
White Magic Lv 8
Crisis Concentration
Turn Tail
HP Boost 1,2,3,&4
MP Conservation(not needed, but useful)
Ailment Resistance

When you equip the skills recommended remember to remove any auto healing and element or damage absorption skills. I was left with a pretty much untouchable Seth and constantly regenerating health which really screwed up the Reversas.

Ultimate Analysis is also useful just to keep track of his health.
[Head Into Dungeon]

Go down to the 24th floor, there you need to walk around and get into a fight with the mini boss "Supreme K". Defend every attack until he uses the spell Divide. He should then bring everyone's health down to one(with the help of Persistence), except for Sed, who should be dead. You then should flee with Turn-Tail(have it on everyone so there's a higher chance you will make it out without a casualty)

If it did not bring everyone's health down to 1, then flee the battle, and use a minor healing spell or potion on them. You then should go back into battle with "Supreme K" and let him cast Divide once more, and that should have your whole party evenly at 1 health, except for Sed.

[Preparations for Professor K]

Use a minor healing potion, or the weakest healing spell to heal your immortals once. That way they should be at a health anywhere between 100 and 111, maybe a little higher. Then heal Sed completely.

The reason we want the immortals to have such low health is so that they can cast Reversa to do some major damage. Also the reason we give them the potions is so that Persistence would let them live through an attack.

Change your formation so that the immortals are in the back, and your mortal is in the front. This is so the mortal can take the physical attack/s.

[The Battle Begins]

The battle should only take a maximum of 4 turns.

Note: He will do counter attacks

Note 2: In round 3, replace Ming with Sarah if Sarah has more maximum health(not current health).

[Round 1]

Have all the immortals cast Reversa twice with Double-Cast. You should do around 60,000 damage depending on your level. All Professor K should do at this point is cast a powerful Regenerate spell.

[Round 2]

Professor K will regenerate 20,000 HP, but don't worry, it wont be a problem. He will also cast Reflect, which wont be a problem either if you follow directions.

Now this will be the tricky part, but if you follow my directions, it shouldn't be hard to do. Have Seth, Ming, and Sarah do double cast with this order of spells. Cast Reflect on themselves, except for Ming, who will cast Reflect on Kaim. Then when you cast the second spell for your Double-Cast, have them do Virus on Professor K. It will get reflected back at you(which you have Ailment Resistance so it wont matter), and it will deplete his reflect(which can only take 3 spells before being warn off). DO THEM IN THIS EXACT ORDER OR HE WILL REFLECT YOUR VIRUS AND YOU WONT BE ABLE TO USE REFLECT. Then have Kaim Double-Cast Reversa, to do 20,000 damage, effectively negating his next regenerate at the beginning of the next turn.

[Round 3]

Professor K will heal. He will then do Annihilation at the beginning or end of this turn(reflect will reflect it, keeping you safe from damage). If you did the last turn correctly, then only Ming will die, unless Sed is still alive, then he will die as well.

Then proceed to Double-Cast Reversa, dealing a hefty amount of damage. If he does not die this turn, then continue to Round 4.


This round is simple really. Professor K will heal again, and you will Double-Cast Reversa on him, sending him to his grave. If he didn't die this turn, then you did something wrong, or you have really bad luck.

Credits: Turonel, the guy who pretty much made up this tactic. Then there's me of course. I added in that Reflect would reflect his Annihilation spell. Xebu added in the tip to take off regenerate items/skills.
