Sephiroth has a very long reach with his sword. Do not underestimate your own
reach. Using the MP Rage abilities, you should gain MP every time you get hit,
enough to cast Cure. Obviously, this makes things easier if you're not spending
time using items to regain your precious MP. Hit him when he's open, and try to
avoid getting hit. Wait for your opening, just don't swing blindly. You'll die
if you keep doing that. The basic strategy here is to whittle him down slowly
but surely (hence the emphasis on defense and HPs), while ensuring that you stay
Sephiroth uses Basic Sword Slash, Teleport Sword Slash (when you combo),
and Flame Pillar. Dodge Roll his Basic Sword Slash if you can, or parry it if
you're really good. He will run all over the place, and attack you at different
angles. If you get hit, don't fret. You *NEED* to get hit in order to keep your
MPs up. This is very important, as your MPs will cure you. Using Cura or Curaga
if you have it, you should pretty much refill your HPs with 1 casting. You may
also use whatever form of Aero you have, but at 2 MPs casting cost, I normally
skip it. As discussed in the equipment section, you might want to even use a
weapon that enhances your magic power and MPs. When he does his Flame Pillar,
that's your chance! Dodge Roll away from him quickly, then use your Strike Raid
to hit him through his flames. After a few of these, his life bar should begin
to move. You may try and normal combo attack him here, but I don't recommend it,
because more often than not, he'll use Teleport Sword Slash, and hit you from
behind. When his life gets down to when the Yellow bar is visible, he'll
teleport and say "come on".
Sephiroth will start doing Teleport Slashes and become in my opinion,
slightly faster. Maybe he just attacks you more often. But the big thing here
is his Sin Harvest. He'll teleport away from you into a corner somewhere, then
he'll say "Sin Harvest" and have a rainbow-like glow around him. Then you'll
notice that same rainbow-like glow over your head. At this point, it's too late.
You're gonna get hit by it, and your HPs will now become 1, and your MPs will be
0. Directly following this, he'll use a Teleport Slash, and impale you. Here's the
strategy: Sin Harvest is your time to nail him. Do not get close to him and hit
him, unless you just happen to be near him when he teleports and starts doing Sin
Harvest. If you interrupt his Sin Harvest, he'll immediately go into a Flame
Pillar. This isn't good if you're standing near him. Stand away, near the center
of the arena, then when he teleports, quickly press R2 to lock onto to him. If you
hear "Sin Harvest", quickly use your Strike Raid to nail him. It will interrupt his
Sin Harvest, making you immune. If his Sin Harvest attack manages to go through,
use an Elixer right before it actually affects you. If you time it correctly,
you'll go through the item animation, Sin Harvest will hit, then your item will
take effect. This is why you have Second Chance and those Elixers... just in case
it hits. After that little exchange, dodge roll and/parry his Basic and Teleport
Slashes, then wait for him to use Sin Harvest again, and repeat. He'll also use
Omnislash for the first time. You can either get hit by this and cure like mad
during it, or use Strike Raid to become invincible. I normally get hit a few times
at the beginning of this to regain MP, then cancel into a Strike Raid to avoid
the final hits of his attack. When he's done with his Omnislash, combo him, or
continue to hit him with Strike Raid. Just get some hits in. After you knock his
life down to where the Green is just barely visible.
Sephiroth gets really angry here. A black and green vortex will surround him,
and he'll have a white glow. Instead of relying on Sin Harvest, he'll
be hurling other nasty voodoo at you, namely Darkness Balls and Meteors. While
he's doing Darkness Balls, you can hit him. So make use of it. You'll need to cast
Cure frequently here, so don't hesitate. When he does his Meteor attack, he's
invincible (at least from my testing). Avoid the meteors as best you can, and
quickly pop out the cures. Occassionally he will use Sin Harvest during this phase.
Don't let it throw you off guard! He uses it infrequently here, and often at
strange times, like right after his Meteor Shower. Sometimes he'll just do a
Teleport Slash after it, and sometimes he'll teleport into Sin Harvest. My advice
is to *NOT* cast Cure after the final meteor blast, and wait to see what he does.
If you hear Sin Harvest, nail him with Strike Raid. If not, dodge roll, then Cure.
He'll also use Omnislash here again as well, and it will be more powerful.
Just repeat the strategy you used in Phase 2 for that, and you'll be okay. He'll
infrequently use Flame Pillar, especially if you're close to him.
Try and dodge roll away, then launch into a Strike Raid attack to hit him for
some damage. Remember to cure! After this phase, he's dead.
Can't beat him?
Don't worry. You will die a lot until you get used to his
incredible range and his timing. If you're dying in the first phase, either you
aren't curing properly, or you don't have enough defense. Try levelling, or
synthing items like Defense UP and Gaia Bangles. If it happens during the second
phase, it's probably due to Sin Harvest. You must quickly press R2 to lock onto
him, then nail him with Strike Raid. If you can't seem to do that, rely on
Elixers. Get your Elixer ready when you see him doing Sin Harvest, then quaff
it just before Sin Harvest hits. If you're dying during the third phase, it's
either from Sin Harvest, or from his Meteors. I never died from his Omnislash,
becuase you can cure in the middle of it. If you're having trouble against that
move, raise your defense or use Strike Raid during it.
Save your game before fighting: Unless you have 99 Elixers, you aren't going
to want to waste them and not kill him. Load your item slots up with Elixers,
get your abilities you want, equip the stuff you want, then save. If you die,
just reset, so you still have your Elixers in tact.
What you win for killing Sephiroth:
After you defeat him,
you'll gain a great deal of exp. 18,000 to be exact. Sephiroth will just
stagger back, float up, and disentegrate into particles of energy. Whether or
not you killed him, or he just teleported away is up for debate.
Also, you'll gain his biographical information in Jiminy's Journal.
Here's the quote from the journal entry:
"Once known as the greatest of swordsmen, his wehereabouts have been unkown for
some time. He challenged Sora to a on-on-one duel. No one knows why he has
suddenly returned. Apparently, he and Cloud have crossed paths before."
