Final Fantasy X/Original: Difference between revisions

It takes one hit to kill the head which will stop Ultima Buster's most deadly attack. It then takes one hit to kill of each the arms, which should be killed as soon as they come back. The main body of Ultima Buster has 5 million HP, but doesn't counter anything making this battle surprisingly easy. Once you have killed the head proceed to just using quick hits on the body until it dies. On Ultima Buster's turn he will either use a single physical attack, which depending on your defence and HP you may survive, or use Ultima. If your magic defence is low you may need to call an Aeon to block Ultima Buster's turns, or make sure to have Auto-Life on one of your characters, but other than that this is actually one of the easiest original creations. If you can easily defeat him, Ultima Buster drops weapons with Triple AP, Triple Overdrive and Overdrive -> AP on them. If you don't have them already, these weapons are obviously fantastic for gaining sphere levels, but they also sell for a few hundred thousand gil which makes your job of maxing out the sphere grid a little easier.

Okay, this is sort of difficult, and I suggest having 255 in at least strength, accuracy and agility (you can get strength spheres by killing the juggernaut.) You'll also need Quick Hit to finish him off as quickly as possible.  For weapons, I suggest the fully upgraded celestial weapons (or any weapons that have break damage limit.) For armor, try to get as close to the following as you can:  Auto-Shell, Auto-Protect, Auto-Haste, and Auto-Pheonix.  You can get four-slotted items from O'aka in the Macalania Forest, at the junction between there and the Thunder Plains.  Now, if you don't have those abilities in your armor, it's okay, you can survive without them.  Just make sure EVERYONE in your party knows Auto-Life, and you have at least 4 Mega-Pheonix's.  You should have Auto-Life on (preferably) one person at ALL times.  This way, when Nemesis uses either Armageddon or Ultra-Spark, he'll be revived, and you can use a Mega-Pheonix. Now, whatever you do, do not attack with anything besides Quick Hit, since he counters Attacks, Overdrives, Black/White Magic and items with Ultima, which hurts. Trust me.  You should use Quick Hit since he is immune to all status ailments, and skills are the only things he won't counter, and you can hit repeatedly a heck of a lot more quickly with Quick Hit.  Now, just unload everything you can on him, hit after hit.  It should take around 15-30 minutes for the person with average stats.  I have 255 in all stats (besides luck), and it took me 10 minutes, but that's only if you're willing to work for it.  Make sure at least one person has Auto-Life, and everyone has Auto-Pheonix, otherwise the battle could be lengthened to around 45-???  minutes.  Not fun, at all.  If you can survive his Ultra-Spark ability, watch out, because it gives you status ailments (I know poison for sure, and I think curse, but I'm not positive.  There could be more, but I'm not sure, since I haven't lived through it.)  But, I must say, the key to this entire battle is having one character with Auto-Life, lots of Mega-Pheonix's if you're not all that strong, but on average around 4-5, and everyone having Auto-Pheonix in their armor.  Don't use overdrives, regular attacks, black/white magic (on him, it's okay to use it on yourself), specials, or items (once again, okay to use on yourself, just not on him.  Don't forget to grab Nova from him for Kimarhi. (Incase you don't know, Nova is Kimarhi's ultimate overdrive.  If you want to see it, just Lancet him and run, get Kimarhi's overdrive and use it, or fight Nemesis and wait for him to use Armageddon.  Same thing, different name.)  Well, that's about all I can give you, so go out and get that Mark of Conquest.  Happy Gaming!
