BOSS : Shadowseer/Darkness God
HP : 278,078

One of the clan's Mob Hunt mission from Monblanc which named 'The Seer'. This mission will show after completing various mob hunt from Clan HQ, it's rank S.

When you're handling this mission, back to Pharos at Ridorana after the events.  So now an elevator available in 1F, take it to underground B1F. Now you have to collect enough Black Pearls from killing monsters, fill those Black Pearls onto the Altars at four different corner to get to lower floors. Below is the number of Black Pearls for each Altar before to the bottom level.
(defeat Phoenix optional boss at B1F)

B1F - South-West 6, South-East 3, North West 9, North-East 18
B2F - South-West 18, South-East 15, North West 9, North-East 15
B3F - South-West 12, South-East 27, North West 21, North-East 15

Also defeat the Phoenix optional boss above at B1F while you're going through. Once you have done, take the elevator to Unknown Goal which is the most bottom. You can't escape from the fight, better back up to save before fight against this dude.

The boss knew many spells included elemental or non-elemental, normally he will show them later. Cast support spells on your party before entering the arena.

1. Beginning
The boss has Immobilize status in his normal attack. Other, he will use Darkness and Shining Ray randomly, both of them deals large damage on your characters in an area. You can equip those Dark element absorber such as Demon Shield, Black Mask to absorb the Darkness, for Shining Ray which is Holy element, you can equip those Holy absorber such as Sage's Ring and the White Mask to absorb it. If you don't mind to always change your equipments, just pay attention when he's charging Darkness, equip those Dark element absorber, when he's charging Shining Ray, change to Holy element absorber. Remember cast Dispel to him for the first.

2. Facing other bosses - 1
When the boss leaves around 75% HP, he will summon out Pandaemonium, Slyt, Fenrir which you fought in each Ascent, and Phoenix optional boss which you fought in Subterra B1F. Now you can hit Shadowseer/Darkness God since he has builded up the barrier, all you need to do is focus to defeat other bosses one by one. During this moment, pay attention on what was Shadowseer/Darkness God is going to do, he will keep on attacking your team with different move, the
worst thing is will blow off your MP anytime. Normally this boss would invert your HP/MP after your MP get drained, if he doesn it, your will be switch at very low HP or even death. Use Charge (technick/skill) to refill a little MP before Invert came. Use X-Potion to recover instantly after you get inverted since item is always faster than spell. After that you should have full MP, so cast Curaja and other useful spells before your MP was drained again.

3. Facing other bosses - 2
Another annoying move is Curse, which will send you some very bad statuses. Equip Ribbon for your healer when he readies Curse (be sure always read the information message on the top left screen), once the Curse sent, cast Esunaga to cure your party. If you didn't get Ribbon before, better set a Gambit to use Smelling Salts for everyone. The toughest part is Fenrir summoned, I recommend use a shield to block Fenrir attack, although you can't block every single hit,
but at least you would get lesser attacks from him. As for Phoenix, Dispel and send it Blind status. Like mentioned on the Phoenix boss strategy, the faster you sent the Blind, the easier this will become.

4. Final showdown
After all, Darkness God's barrier should be gone, attack him again. Since its name call Darkness God, no doubt for using Holy, Excalibur could help lot too. Remember, the damage of each weapon attack to the Shadowseer/Darkness God will be returned 7% on your own, let say your damage is 5000, your character will get 350 damage him/herself. As his HP getting lesser, his defence power will be highly increased, but if you continue attack him with all your best weapons
with a healer support this fight should be done safely, just take a little longer to reduce his remaining HP.

BOSS : Humbaba Boss/Humbaba Mistant
HP : around 308,000

One of the two bosses that you must fight before gain Chaos esper. For more details about the ways to get this battle, you can look for Chaos - King Of Reincarnation under "Esper/Summon" section.

Compare to Fury, this boss deals slightly lesser damage for normal attack, but the special skill is still dangerous. Dispel him at the beginning, you can also send Sap, Silence and Slow to him, Silence doesn't matter, but make sure send him a Slow status. Same as other battle, heal and cure your ally in the entire battle, use Protect to reduce the physical damage. Things that you should pay attention are the moment when the boss is near dead, he seems like very easy to perform a series of combo hits. Cure Immobilize and Disable status as soon as possible because he can attack your character many times in a turn when the character with Immobilize status.

After defeating this boss, you will get the map for Necrohol Of Nabudis.
