But I'm asking about MY situation.

Everyone's about level 75, I've beaten every mark but him, and gotten every Esper. I have every piece of equipment in the game except the Grand Helm, Grand Armor, Danjuro, and Yagyu Darkblade (which I know is useful and I am in the process of trying to get, have an ongoing chain in the Lhusu mines at about 18 so far with my game paused as I take breaks) and the Wyrmhero Blade (well DUH!!).
Everything else I have, even the Zodiac Spear and Tournesol.

So... have I got a chance? Or should I bother with the Yagyu (I'm already almost there anyway), or level up more? And If I can pull it off, any tips?

Most people battle yiasmat with lvl 99 characters and the gambit: Ally: status KO: Full Life

This thread hasn't been posted in for weeks and there's another thread...like it says in the title...

Fuck the yagyu darkblade.
Masamune ftw.

(it's possible to get 2 of them, too).

How is that?

Also, I've beaten every mark in the game and when I went to talk to Monteblanc he said there wasn't any more marks for me to hunt. So does anyone know how to get the mark?

Have you beaten Hellwyrm yet? That's a prerequisite, I believe.
It is possible to synth a 2nd masamune. You need Gemsteel x2, Orichalcum x3, Mallet x2, all of which are a pain to accumulate. However, if you did it for the Tournesol, it would be well worth your time to do it for a 2nd masamune (esp. since it's the superior weapon against Yiazmat.)

Heh, I actually planned ahead and Tournesol did become available before Masamune, but I didn't buy it until I got the other Orichalcums for Masamune so that the Gemsteels would count for both.

I just beat him and this was my strategy. I never once ran out of Mp, nor did I ever use the save crystal. It took me a grand total of 3 hours and 12 minutes.

Characters: Ashe (Mage), Baltheir (Fighter), Vaan (Combination)

(It can be done with other characters; however do not use Fran, Balthier, or Penelo as your combo player with the long range weapon. They all have a 0.2 second delay with ranged weapons, in this fight every second counts.)


Equipment:

*Mage:
- Weapon- Staff of the Magi
- Helm- Circlet
- Armor- Lordly Robes
- Accessory- Sage's Ring
(This creates a high Magick Power for your mage)

*Fighter:
- Weapon- Masamune
- Helm- Golden Skullcap
- Armor- Maximillion
- Accessory- Genji Gloves
(This creates a strong, yet quick fighter to rack up combos)

*Combo:
- Weapon- Fomalhaut
- Off-hand- Dark Shot (Yiazmat is weak against Dark element)
- Helm- Circlet
- Armor- Maximiliion
- Accessory- Sage's Ring
(This is a balanced fighter, leaning more towards Magick)


Gambits: (Gambits need to be in this order)

Mage-
* Ally: Balthier (Fighter) -> Reverse
* Ally: any -> Arise
* Ally: any -> Shellga
* Ally: any -> Hastega
* Ally: Balthier (Fighter) -> Bravery
* Ally: any -> Bubble
* Ally: Balthhier (Fighter) -> Berserk
* Self -> Libra
* Ally: Vaan (Combo) -> Bravery
* Ally: Status=Sap -> Remedy
* Ally:any -> Reverse

Fighter-
* Foe: highest max hp -> Expose (Get about six successful one then get rid of this gambit for the duration of the battle)
* Foe: highest max hp -> Attack

Combination-
* Ally: Balthier (Fighter) -> Reverse
* Ally: any -> Gold Needle
* Ally: any -> Arise
* Ally: any -> Chronos Tear
* Ally: any -> Bubble
* Ally: Balthier (Fighter) -> Decoy
* Ally: any -> Shell
* Ally: any -> Haste
* Ally: Status=Sap -> Remedy
* Foe: highest max hp -> Attack

Reserve- (This person will come out in case two or more die. Let them arise then regroup your main fighters)
* Ally: any -> Arise

Yiazmat attacks:
* Rake- Basic attack that can cause stop (Countered with Chronos Tear)
* White Breath- Basic attack
* Stone Breath- Basic attack that can cause petrify (Countered with Gold Needle)
* Cyclone- Brutal Attack w/ movie sequence. Massive Hp and can cause sap (Countered with Bubble and Remedy)
* Deathstrike- Attack that causes instant death (Countered with Shell. Shell will reduce the % this attack works)

Basic Strategy:

This boss is an endurance battle as so many have said. All my character were level 99 when I did this. For one thing you are going to die during this battle, but don't fret. If two or more of your party dies run into a side area and regroup; however Yiazmat will begin casting Protect, Shell, and Regen so Dispell him ASAP. I herded my group into some steps so my Fighter was in the ring with Yiazmat while the Mage and Combo stayed on the stairs. Keep the combo as your leader so Deathstrike will most likely target them if the Fighter dies. Another important spell to use MANUALLY is SYPHON. If your Mage or Combo run out of mp use SYPHON on your FIGHTER, the Fighter will regain mp ridiculously fast because they are constantly attacking and being attacked! Yiazmat will DOUBLE LEVELS about halfway through, but continue with this and you will be fine. The damage cap after he does this is around 7000, but with Masamune you will combo 7000, thus damaging Yiazmat for more. (Greatsword: 9999, Masamune: 7000 x4 = 28,000). Watch out for the traps and have a good time! Make sure you have plenty of the items referred to above and you should be alright. If you have questions about where to get weapons or armor feel free to ask! Happy Gaming!

Okay, I basically just went with my own strategy on about Level 85 average for my main group and have him down to 3-4 HP bars. I think I'm going to win, but I want to be certain. However, I'm unclear about some of the stuff I've read regarding leaving the battle. I want to know from anyone who's done the fight before what would happen as far as Yiazmat's HP status if I were to try any of the following:

- Exit the battle, save the game at the nearest save point and quickly return
- Exit the battle, save, go to another area and shop for items and return
- Exit the battle, save, and reset


I currently have the game paused.

OK, you can definitely return and save, and I'm pretty certain you can reset (otherwise there'd be no point in saving).

However, I don't think you can leave Ridorana to buy items. I've never tried it, but I'm getting close to Yiazmat on my new save, so maybe I'll see what happens...

I... lost. And I wasn't able to make it to save either. But it's all right. I'm going to take this as another lesson as to what being overconfident can do when it comes to playing this game. And I'm also going to consider it a trial run for when I try again. Since there's really no pressing reason to beat him quickly, I'll just go back when I have even more stuff. I figure that since I almost won this time, it should be a lot easier if I just build my stuff up some more.


And Slavka, thanks. I do know that if you exit the battle and reenter, it displays "Stage 2," "Stage 3" and so on. You know, this evening, I think I'll just do a quick run, test out each of those items I listed myself and see what the results are. No reason not to -- I'll just save/reset as needed/desired.

FYI, casting berserk on a Masamune'd, Genji'ed fighter is extremely helpful.

Worth noting, thanks. Anyway, success on all three of above items -- you can leave and save/restore, you can reset, and you can leave the area and return.
