I need help beating Sin in Final Fantasy X. Any suggesions or strategies?

Question

Okay, so I'm at the part of Final Fantasy X where you're on the airship after defeating Sin's left and right fins or whatever. The next part, the part with the rediculous overdrive, I have played seriously about 14 or 15 times now and I lose every time. I must really suck, because everything I've read about this part says it's easy. I really need help because I would prefer to finish this game soon. I've been playing it for about 4 or 5 years now. I restarted quite a bit :)

Answer 1

If you've lost that many times in a row, you probably genuinely aren't at a high enough level to take on Sin yet.

Your best strategy is to defeat him BEFORE he has a chance to use his Overdrive. I levelled up insanely before I fought Sin, and I took him out in three or four hits.

I'd suggest backtracking a bit, and spending some major time levelling up. Get Break Damage Limit on the weapons of your hardest hitters... Auron, Wakka and probably Tidus, depending on how you've developed him. Teach Lulu Doublecast, and have her use Flare and Ultima against him.

Another smart idea is to make sure that EVERYONE'S Overdrive gauges are fully charged before entering battle, even your Aeons. Do you have the harder-hitting secret aeons like Anima and the Magus Sisters? My Anima routinely does 99,999 damage with his Oblivion Overdrive... it's about enough to take out anyone.

There are a lot of ways to go about this, but I'd strongly suggest spending some serious time levelling up. Obtaining the Celestial Weapons can't hurt, either... most of the time, my Tidus and Auron deal around 15,000-30,000 per hit with their Celestial Weapons.

If you've been playing for four or five years, going on some side-quests to obtain these things should add some fun and variety to your gameplay. You've still got a ways to go from the point you're at... I don't know if you've read any spoilers, so I won't say anything that might spoil it for you, but you've got some even more challenging battles coming up, that are going to require every bit of strength you can obtain.

Hope this helps... and have fun! FFX is one of my all-time favorites, if you can't tell. :)

Answer 2

============
AIRSHIP DECK
============

On top, you’ll see a scene where Tidus shows Yuna her sphere. After that, the
battle with Sin begins.

#############################################################################
BOSS: LEFT FIN (SIN)
#############################################################################
HP: 65,000
AP: 16,000
Gil: 10,000
Items: HP Sphere
Equip: Sidewinder
Attacks: Gravija, Negation, Physical attack (side swipe)
Steal: Mega-Potion

This is rather easy. Just move in and do all your stuff, especially physical
attacks of Auron and Tidus. You may use your aeons here but I suggest that
you save it for later. First, if you use Haste or any other stat altering
effects, Sin will use Negation against you. It’ll remove those status. Beware
also of Sin’s Gravija attack, which cuts off around 80-90% of your current
HP.
#############################################################################

After that battle, Cid will sever the arm of Sin. Now, you’ll have to do it
again with the other arm.

#############################################################################
BOSS: RIGHT FIN (SIN)
#############################################################################
HP: 65,000
AP: 17,000
Gil: 10,000
Items: Lv. 3 Key Sphere
Equip: Rock Buster
Attacks: Same
Steal: Mega-Potion

As for the Right Fin, just do the same strategy you did on the other fin of
Sin.
#############################################################################

After the final battle with the fins, you’ll have to target sin’s weakpoint
itself. A battle begins anew.

#############################################################################
BOSS: SINSPAWN GUNAIS & SIN
#############################################################################
HP: 20,000 / 36,000
AP: 29,700
Gil: 20,000
Items: Return Sphere x2, MP Sphere x2
Equip: Blessed Bracer, Light Bangle
Attacks: Venom, Level 1 Magic, Gravija
Steal: Star Curtain

In this battle, concentrate on attacking the Sinspawn so that you’ll have a
clear shot at Sin. You may now use your Aeons to help you beat these 2. As
for their attacks, you’re most likely used to getting poisoned and having
your HPs at a very critical stage.
#############################################################################

After those intense battles, Sin will finally go down. At the airship, save
your game. Then, go to the deck and talk to Yuna. You’ll see some scenes
here. After that, Rikku will tell them that something is happening to Sin.
Sin transforms and is now waiting for Tidus. Go back and save then go to the
deck for the confrontation with Sin.

#############################################################################
BOSS: SIN
#############################################################################
HP: 140,000
AP: 20,000
Gil: 10,000
Items: Lv. 3 Key Sphere
Equip: Echo Bangle
Attacks: Physical Charges
Steal: ?

This is an ultra-hard fight, if you don’t know what to do. I used aeons and
it didn’t work since the Overdrives take too much time and Sin will be able
to open its mouth and unleash its 100% win attack. Follow this strategy that
I used. Before the battle, put Tidus, Auron, and Yuna. Then, have Tidus cast
Hastega on everyone. Sin will still be approaching at this point. Now, let
Yuna cast Protect on everyone and after that, exchange Yuna for Wakka. Let
Tidus cast haste on him. By this time, Sin should be close enough to be
attacked physically. Let Auron use Armor Break and Mental Break (a
preparation for your final attack against Sin) and let Tidus and Wakka hack
and attack Sin. When Sin’s HP is around 18,000 left, let Yuna come in and let
her cast Bahamut in Overdrive (do not call him when he is not in overdrive or
else this final attack won’t work and Sin will banish everyone). This will
defeat Sin.

Strategy from: [e-mail]
------------------------------
For the big Sin, if your Tidus is a little stronger than average, he will
have Quick Hit. If you've saved your Friend Spheres, get Auron and, if
possible, Wakka this skill. With Hastega, this will SURELY win the fight,
ESPECIALLY with Armor Break. Also note that you CAN get Anima by this point,
and Oblivion does incredible damage (40,000, I think?) as well as her
attacks.

Strategy from: Matt DeCicca ([e-mail])
-------------------------------------------------------
I have a very effective and "foolproof" way to beat Sin. First of all, you
must have Anima and her strength increased to at least 94. Then you must have
both Yuna and Anima in overdrive so this way, you can unleash 2 overdrives
from Anima(this is achieved with Yuna's Grand Summon overdrive, which is what
you do when you come to battle Sin for the first time on the airship.) Each
overdrive will damage Sin for about 58,000 some damage points, if not really
close to that figure. Both overdrives will sort of "weaken" Sin for Anima to
do a regular attack and beat Sin. Only thing is though, for me he never got
to his 100% win attack in time, so therefore it was really easy for me. Well,
he did, but he never used it after the two overdrives. For any of you, you
may not get so lucky the first time, so just keep on trying until you get to
attack him with the overdrives and the regular attack.

Answer 3

get the ability to break damage limit....once you can do that, everything should be A.O.K
