BOSS : Omega Mk.XII
HP : around 12,000,000?

Before plan to face this boss, you must unlock Yiazmat Mob Hunt mission and collect all Esper, or defeat Yiazmat and collect 10 Espers? Go Crystal Grande (The Great Crystal) upper layer, please reference to this map,

Crystal Grande
 
Since you've went through this map on the road to Ultima Esper fight, you should have unsealed some of the gate in Map 3. If you left the Crystal Grande, all the '1st' gates will reseal, so you need to unseal the gates if required.

Now you need to unseal Gate Taurus 1st to reach the arena. Just get back to the Save Crystal at Map 4 through the teleport XX...

- Push the swtich for Gate Aquarius.
- Return to Map 3 through the teleport XVIII
- Unseal the Gate Aquarius 1st (base on how you unseal the gate when you're going to Ultima Esper fight, just make sure to unseal Gate Virgo and Libra 2nd.)
- Now push the switch for Gate Capricorn, then unseal Gate Capricorn 2nd.
- Back to switch for Gate Taurus and push it, rush to Gate Taurus 1st and unseal it.
- Take XXI to the arena.

Omega Mk.XII's attack style is nothing special, the difficulty is the damage amount of Omega, each hit might kill one of your characters, with its higher speed, this boss can kill your team within a minute. Recommend cast Reverse and Decoy on one character for the entire battle, so Omega will keep 'healing' one of your character for the entire battle.

Reverse is to turn over the damage and healing amount, Decoy is provoke enemy focus to attack one target, so if the character has both these spells' in once, Omega will only attack this character, same time its damage will heal that character. Make sure set two other characters' Gambit to keep recasting Reverse and Decoy when they're gone, also keep Haste on these two characters to speed up casting the spells. For more easier, equip Hermes Sandals for the character who's position to cast Reverse or Decoy. Another thing is avoid to use any elemant attack on this boss. When Omega's HP leave around 20%, its defence and attack power will be raised automatically, but if you can keep with the tactic above, it doesn't become a problem.

BOSS : Yiazmat
HP : around 50,000,000


The last Mob Hunt mission, it's located in Ridorana Cataract, the round section at South where knowing as Colosseum. You must complete all other Mob Hunt mission and defeat Hell Wyrm/Majinryuu optional boss, then back to Clan HQ and talk to Montblanc to receive this mission.

#- General Strategy
It's like a enhanced version of Hell Wyrm/Majinryuu (above), and you can run away anytime like Hell Wyrm/Majinryuu fight. With everything for the Hell Wyrm/ Majinryuu battle (except the weapon has some changes), and your main team raise above than 70 level, you can fight this boss in a long period without escaping. However, Yiazmat's weakness is Dark and it can absorb Holy, so Excalibur should be keep away from this fight.

Some weapons which are not using in the Hell Wyrm battle,
- Yagyuu Darkblade or Orochi, Fomalhaut + Dark Shot

Basically, you can just use the Gambit setup for Hell Wyrm/Majinryuu (above), just to add some Gambit to cure other negative statuses, be prepared to cure Petrify, Stop, Sap. Also prepare some Phoenix Down and Arise spell to revive your team from time to time since Yiazmat will use Deathstrike to your team randomly. But I've noticed Yiazmat likes to use it when the spotted character is near or at the staircase, so if you hate Deathstrike, don't stay at the staircase, fight it at the stage. Sometimes, Death Strike gives you a little benefit since it takes Yiazmat longer time to recover, means Yiazmat needs a few more second to start its next more if it does perform Deathstrike on you.

Later, the Death attack come even faster, maybe Arise would be useless, just keep on using the Phoenix Down to revive your ally. After half of its life, its defence and attack power will be raised. Same time, it might cast Reflecga spell to you, make sure you don't cast the healing spells when you got Reflect status. To reduce the damage of Cyclone Tornado, you can equip the Windbreaker (light equipment) when it's going for this move, it can reduce 50% damage of
Wind elemantal attack. Since it's like Hell Wyrm, so you can flee from the battle and heal your party on the Save Crystal, just be sure Yiazmat is not in Regen status when you leave.

#- Overwall attack trick
But there's a little trick to trap Yiazmat and attack him without worring much. Everything has already mentioned in 7a-2 Mob Hunt section, check it out for the details, and here is the basic steps to trap it:



You can actually use this trick for 95% of the battle. Only problem is when Yiazmat down the 2 life bar (1 red dot left under his HP bar), he will restore his HP, so this trick doesn't work anymore, you have to close combat to stop him from restoring HP. And it's not a Regen, so yuo can't Dispel it. So be sure you save your game when Yiazmat remains 2 life bars.

Again, this is a tough boss, by using the overwall attack technique, you can be at lower levels like 65~70 since he can't attack you. But in the end, you will eventually fight him face to face, and you should be at least 75 level. Only attack and cure isn't a good idea unless you're over 90 level, you can have a try for the tough fight like other bosses. Or else, I recommend either use Decoy + Reverse tactic or use Reverse to all character during the fight, means transfer Yiazmat's powerful attack to heal your team, that's the reason of using Reverse.

BOSS : Hell Wyrm/Majinryuu
HP : around 8,500,000

Located in Sochen Cave Palace, the West area. Before you can enter the arena, here are the things that you need to do:

- Clear Vyraal (rank A) Mob/Mark Hunt mission, after getting the rewards and give the Viera Rucksack which dropped by Vyraal to your client, she will give you the Dragon Scale.
- Now head to Cerobi Steppe, find the windmill in the North-East section where you hunt the Vyraal.
- Examine windmill No.10 to trigger a scene, then pass Dragon Scale to that NPC for Ageworn Key.
- Return to Sochen Cave Palace, go to the section just after the five ways area, there is also the section before the boss. You can see in your map it's a circle area with a cross in the central (Destiny's March), you have to run through the circle follow the clockwise. And you must reach here from South, enter the circle area from East, then go South > West > North > East, if you do so, the road to the arena will be unlock.
- Now enter to the door to West section, use the Ageworn Key to unlock the arena.

This boss has lot of HP, make sure set up your gambit system for this long battle. There is a trick to beat this boss without pressure, you can actually flee from the battle to heal your party, back to the battle later, and it won't restore the HP.

If you decided to have a long battle without escaping, you should get yourmain team characters over 65 level or at least 60 level with some recommended equipments below, the more of these equipments you have, the easier this battle will become. And the equipments are:

- Weapon: Excalibur, Masamune, Golden Axe/Scorpion Tail, Whale Whisker...
- Acc. : Ribbon/Power Armlet, Bubble Belt, Sage's Ring, Hermes Sandals...
- Item : Phoenix Down >20, Chronos Tear >30, Gold Needle >30...
- Other : Golden Skullcap, Maximillian, Mirage Vest, Magepower Shishak, Brave Suit, Demon Shield, Zodiac Escutcheon...

Note:

Shield doesn't have much usage actually, the Demon Shield, Zodiac Escutcheon are for you to block the Dark and Thunder spells from Hell Wyrm in case of your strategy is not stable under certain situations.

The Decoy idea from Wesley Watson is quite good, and I've slightly changed the tactic to be easier. This is a long battle, althought you can use the Decoy + Reverse tactic, but don't recommend to use it for the entire battle.Anyway, here is my Gambit setup for this battle.

--------------------------------------- *Note:
| Character 1: Fran (attack)         | - Character 1, Gambit 3
| 1. Ally: Any = Phoenix Down     | Cancel this Gambit if you have
| 2. Ally: Any = Chronos Tear      | this character with Brave Suit.
| 3. Ally: Fran = Bravery*             |
| 4. Ally: Any = Bubble                  | - Character 2, Gambit 7
| 5. Ally: HP <50% = Curaja         | Use this Gambit only if your
| 6. Self: MP <10% = Charge        | team is weak on Def.
| 7. Foe : lowest HP = Attack        |
|                                                         | Hell Wyrm is weak against Holy,
| Character 2: Ashe (lure)             | needless to say, Excalibur deals
| 1. Ally: Ashe = Decoy                   | the largest damage to this boss.
| 2. Ally: Any = Arise                      | Cast a Bravery to the ally with
| 3. Ally: Any = Chronos Tear       | Excalibur can send the maximum
| 4. Self: HP <60% = Curaga         | damage to Hell Wyrm.
| 5. Self: MP <10% = Charge        |
| 6. Ally: Any = Bubble                  | As for Reverse, you can cast it on
| 7. Ally: Any = Protectga*            | your Decoyed character when he/she
| 8. Foe : lowest HP = Attack        | in full or over 80% HP, so basically
|                                                         | you don't need to worry on casting
| Character 3: Penelo (attack/mage) | healing spell on the character with
| 1. Ally: Ashe = Decoy                  | Reverse status.
| 2. Ally: Any = Arise                     |
| 3. Ally: Any = Chronos Tear       | When Hell Wyrm down to 25% HP, it'll
| 4. Ally: HP <50% = Curaja         | use Invert each two turns, it's to
| 5. Ally: Any = Gold Needle         | switch between your HP and MP. You
| 6. Ally: Any = Hastega                | can simply use Renew on this ally
| 7. Ally: Any = Bubble                  | manually. Better start casting Renew
| 8. Self: MP <10% = Charge        | before the effect of Invert is sent,
| 9. Foe : lowest HP = Attack        | so you should able to heal before
--------------------------------------- the next attack from Hell Wyrm.

The Judgement move is the strongest attack from Hell Wyrm, but it doesn't show this much, but when it performs this move, you might be killed after a short while. Make use to cure the Stop from this move, and it's better if you have accessory to prevents it. Anyway, this move seems to destroy the whole arena, but doesn't mean this move can attack everyone in the arena. Like common area magic, Judgement is a skill to attack all target in an area, if you're out of this area, you will not take any damage. During my battle, Ashe is supposely to be the target of Hell Wyrm most of the time, I just move a character away from Ashe to evade the Judgement, so probably this character will escape from the Judgement area. To make things easier, just move a character to the back of Hell Wyrm for all the time.

One more additional note is remember that you can always change your equipment, equip Demon Shield or Black Mask when Hell Wyrm use Darkga, equip Flame Shield to block Firage and so on... if you like it.

BOSS : Gilgamesh
HP : 123,103

One of the clan's Mob Hunt mission from Monblanc which named 'Mysterious Man'. This mission will show after completing various mob hunt from Clan HQ, it's rank H/VII.

Once you handle this mission, back to Lhusu Mines. From the Gate Crystal, move to West will encounter him on the bridge. Other than Gilgamesh, you were also face against his beast, Enkidou.

Before anything, just to inform that you could steal Genji Shield on his 4th form (less than 45% HP) and Genji Gloves on his last from (when he start to builds full barrier). This is the only chance that you could get these two equipments, if you miss it, you will never get them anymore. About his form changing, you will see a scene and he will change a different sword, start from second form, it's very easy to be noticed.

Dispel Enkidou for the first, defeat it before you focus on Gilgamesh. You can send Slow to Gilgamesh, other status didn't work on him. Once he's got certain amount of damage, he will change his attack style. In each form, try to steal something from him, you might get some potions, be sure you steal Genji Shield during his 4th form. Also make sure you steal the Genji Gloves from his last form, this equipment can increase your attack combo. Also when he is in the
last form, he will build up the perfect barrier by coming out with his special attack, Ultimate Illusion. Now you can't do anything other than defend, recast the support spells when anyone of them gone. After he does Ultimate Illusion for the second time, the barrier will gone. Now Dispel him and continue your attacks. Again, make sure you have stole the Genji Gloves before end the
battle.


BOSS : Gilgamesh (second battle)
HP : 473,246

After the first fight, Gilgamesh will run to Site 7 which is South-East most of the mines. Before you can reach there, you must clear Antlion (rank A/V) mission, then back to Phon Coast Gate Crystal area, go North-West can see two men there, take the shinning thing beside the sitting man which is the key of Site 11. With the key, you now can get to South-East area of the mines. Before the arena, you should see a Save Crystal.

For this fight, you could steal Genji Helmet and Genji Armor on his last two forms like before. Remember, you can't get these equipments from any other way. Other things that's recommended are Bubble Belt, Genji Gloves with Greatsword, Ninja Sword or Katana, and other best equipment that you currently have, also make sure to always recast Bubble for those who're not to equip Bubble Belt.

Now he is more stronger than the first fight, and Slow doesn't work on him anymore. And he will send Disable, Sleep and Break/Petrify from time to time, actually all these statuses can be avoided, it depends on your character level. Let say the Break, it's belong to Lv.4, and the indication of "Lv.4" means this status can only be affected on the character who's at the multiple level of 4.
For example, character at level 52, 56, 60, 64 ... will 100% get this status unless this character has equiped certain accessory to prevent it. Same theory goes to Disable and Sleep statuses, which are only affect on the characters at the multiple level of 2 and 3. So is better you get a perfect level that is not at the multiple of 2, 3 and 4 before the fight, recommend get to Lv 55, 59, 61. Of cause there're lot more levels are no at the multiple of 2, 3, 4, if you get higher, the battle should be more easier.

At the beginning, Dispel on Enkidou/Enkidu and defeat it immediately like the first fight, but there's a problem when Enkidou/Enkidu in Critical status, you will probably miss alot attacks with you weapon, I suggest use the gun type weapon like Fomalhaut, Antares.., whatever the best guns that you have for now since the gun type weapons have 100% accurate ratio. When your enemy is down to Gilgamesh, change back the best weapons that you used.

Gilgamesh will send you some status at the beginning, beware of Disable, he will send it to all your characters, probably some will miss depends on your characters level as mentioned above or read below for some details. Likewise, Gilgamesh will change fighting style when his HP down to certain level, you can steal some more Genji equipments on his last two form as well, the equipments are Genji Helm and Genji Armor, be sure you don't miss them. His normal attack send Stop to your characters, thought the chance is low, but you must care of it, prepare to heal this negative status. When he's down to around 20% HP, he will put up the Sword of Legend in a special scene, now stop everything, try to Dispel him before he perform Monarch Sword special move. Start from his first Monarch Sword, he will build the perfect barrier again, you have to wait his second Monarch Sword for the barrier gone. Just now if you had successfully Dispel him before the perfect barrier, now you don't have to defensse yourself against him with the Bravery, Haste and more support spells. Now just recast all support spells on your team if anyone of them gone, keep you eyes on the second Monarch Sword, it can deal a large damage on a single character. Revive your character with Arise before Gilgamesh attack the next character, since his chance of combo will be highly increased when he within the Critical status.
After that, continue your attack when his barrier has gone, don't forget to Dispel him if he has recast any support spell.

Level 4 Break can only affects on the characters with level multiple of 4,
eg: level 4, 8, 12, 16...
Level 3 Disable can only affects on the characters with level multiple of 3,
eg: level 3, 6, 9, 12...
Level 2 Sleep can only affects on the characters with level multiple of 2,
eg: level 2, 4, 6, 8, 10...
