Defeating Seymour Flux (You guys should totally pin this [wishes I were mod])

This is the easiest way,

Put all aeons in overdrive in previous battles, equip Yuna with a sensor weapon. Once Seymour's HP gets to 39,996. Summon over and over using overdrives, He won't even get to use Total Annhilation.

As for surviving Cross Cleave, Seymour always casts Dispel before using Cross Cleave. If Yuna or Rikku (use), (and possibly Kimhari if he used Yuna's path) gets a turn before he does it, Cast Protect on any character who's HP is between 1270-2580 or use an item that casts protect, use a Mega Pheonix to revive lost characters if more than one is dead.

When you start, cast Bio with Lulu and use Hastega, especially after being dispeled

Thanks.

I just got lucky with Yojimbo.

It usually costs a lot of money to get Yojimbo at that point in the game,

Good point.

I had no trouble winning that battle and considering there is like 4 threads on this why don't you just post it in one of them instead of starting a new thread:)

best tactic ever - use rikkus "sunburst" it rocks! it does about 20,000 damage!

That tactic (omegaweapon's one) is based on having the right items. This walkthrough is practical and based on an aeon sac. I think it's also worth mentioning a few other points.

-Seymour has about 70,000 life.
-A holy water fixes zombie status.
-I'm pretty sure protect effects "Total Annihilation's damage bringing it down to a reasonable amount.
-Hastega gives you a hell of a lot more turns then you'd get without it.

There's probably stuff I'm missing.

im my oppinion the easist way (not the best way) is to get the wings of discovery at reniem temple mix 2 to get trio of 9999 and use wakkas attack reals dead in 2 hits

The reason why I made this is so nobody complains about Seymour Flux
