after a whole year of trying to defeat Seymour(the third) I KILLED HIM(though he's already dead) anyway, Tidus had the dream about the fayth..blahblah..and then I get the party of Rikku, Tidus and Wakka, not I get the key of something after making wakka aim into the sphere thing, I don't know what to do, I went to the part where the lttle red triangle on the map indicates, and nothing happens, what should I do? please help me..:confused:

This isn't helping, but: A WHOLE BLOODY YEAR!?!?!?!
Also, go back to the save sphere, and head north, i think.

yes, a year sad isn't it?

north there are two ways, easta dn west, should I go <--- or ---> ?

So you're on Mt. Gagazet? Just travel both ways. You'll get training in, which you'll need for the next boss fight.

If you haven't already, you have to throw Wakka's ball towards that sphere-structure at the end of the water tunnel.

which seymour fight the one where he tuns you into a zombie and casts curaga/ja zombie seymour on gagazet

Lionheart Reborn: no, past those..

anyway, I did it but later I face that monster Yunalesca sent, and it makes 2 turns curaga, curing itself 9999x2 so it's like I didn't do any damage! what should I do? casting Reflect on him would disable me from using lulu's magic..so is there anything I should do? aslo, Bio doesn't seem to work on him, I tried to "Bio" him, it does, but doesn't deal any damage after each turn

you mean that azi dahaka? (something like that)...

actually i defeat that thing by using bio...

and i use all my aeons...

if you got yojimbo earlier, you can use zanmato...

You must be talking about Sanctuary Keeper, right? Cast Hastega on your entire party along with probably Protect if you desire, then have Auron use Armor Break and Mental Break on it. Cast Reflect on it, then use your Aeons (preferably in Overdrive) to attack it. It'll instantly kill them, so you only get one good shot. At half HP, it'll start casting Curaga on itself, which will just reflect back to your party. If you want, you can also cast reflect on Lulu and have her bounce the spells off herself. You also need armor that primarily protects against Sleep and Confusion.
