Alright, I am stuck on Jecht inside of Sin where he turns into that weird..

Whatever you do, DON'T use Animas overdrivre in the first round. Go out and do some battles and build all your characters overdrives and unleash them on him in the first round (except Yuna's).

BFA is vunerable to all types of Breaks and if you have full break, then that is even better.

Try to use Flare in combination with Doublecast and Copycat. When he pulls out his sword, switch Yuna in and Grand summon any aeon you want, but my advice would be Anima or Bahamut first.

Unleash all your aeons Overdrives and if he still isn't dead use your two strongest physical attackers and if Lulu knows Flare, Holy or Doublecast then use them.

Be aware that the aeons overdrives entail long recovery times, so he could either heal a lot or wipe out your aeons.

Ok, it is quite easy to beat Ject in side sin all you have to do is fight fieds inside sin 4 a bit to get you a bit stronger also teach bahamut or what ever his name is the move cura or courage to cure your self.

When I fight sin use aron-yuna and waka use aron to attack jeck use waka to hit them, the thing that heals him and use yuna to send out bahamut.

Make sure he is strong- were round 8000-9000 life use his overdrive then when ject has about 4 turns use impulse witch attack ject and the things that heal him (they have bout 2500 life I think) when bahamut is nearly dead use the best cure that you have for him.

I think he goes in to something else as well, I can not remember.

Oh yeah also make sure you have auto phenix on your sheild for all your party, maby cast auto life on a couple as well,

Hope this helped you from dimond dog.

Perhaps you could help me out with my question that I have put in plz help me.

Thanks,

Yay I'm special ^_^. Well first of all try and get your overdrives for tidus (keep using them it should take about 200+battles depending on how many times you used them) Hint don't kill any of the statues as if on is knocked out the other will give you nasty status affects.

Braskas final aeon is vulnerable to all breaks but will only last 1 round possibly.

Make sure eveyone has a go and heres what you do. Use hestaga and make rikku mix up mega vitality (mix potion and stamina tablet) use double cast and flare or ultima. If yuna has the healer overdrive use it until later. When you kill his first form (easy enough) start to use protect regen and talk (tidus) when his overdrive is almost full. Protect will half the damage of his sword and talk will make his gauge go to 0 again twice I think. If your dying grand summon anima and use oblivion twice. If that doesnt do it keep using curaga or albhed potions.

If you have auto life you are one step ahead and it would help if some of your characters have 1mp ability (especially yuna and lulu, just use three stars x20 on a wepon or get their celestials but it's not needed).

If needed summon your aeons and use their overdrives and as sacrifices as you will not need them in the next bit and you don't have to worry about dying in the next bit.

As for the megus sisters catch every monsters (except machinas) on mt gagazet and send belgimine when you beat her megus sisters. Go to they fayth door and open it.

You can not predict their moves like normal. Their overdrive does not break through enemy armor so use armor break first if possible.

Hope I helped and if not tell me what you need to know.
