Final Fantasy X Walkthrough Part 102 Seymour Omnis

Part 102 - The last encounter with Seymour.

Yes, he's at it again! But this time, he's going down for good!

So, what's this boss about?
He has weird discs behind him with the elements showing.
When they spin around, they will tell you the element he will use.
He'll be weak against its counterpart!

When he casts a spell then, he will cast 4x of the element he's currently using.
Mostly he will hit all 3 characters once then randomly with the 4th blast.
This means NUL Spells work great! Spam those and it will minimize his damage greatly and it should be a breeze getting through this.

He will also sometimes cast dispell, so be ready to cast Hastega + NUL spells again.

Be aware that he can also end up casting Ultima.
Ultima is truly powerful, but Tidus, Wakka or Auron shouldn't have a problem surviving it.
As for others, they'll probably fall.

You could help by using Shell or some such I suppose, but remember to consider healing downsides.

All in all, this boss is easy.

And no, I have no idea why Auron liked to make a turn for a charge. Well, okay, I have an idea of what can be causing it. Still funny to keep, though.
