FF10 Bosses

Auron's Overdrive gauge automatically fills at the beginning of this fight. Go ahead and use his Dragon Fang attack against your enemies. You must press buttons quickly in the correct sequence to get a more powerful attack. Don't bother using Auron's Power Break, because this boss only uses one attack--casting Demi. Just keep hacking at it and you will defeat it. Its tentacles gradually disappear as you reduce its HP. You need not use Potions to keep your HP high. Demi is a percentage attack, meaning that it alone can't kill you. Auron's Overdrive should have wiped out the lesser Sinspawns, so don't worry about that.

Don't let the ultra-high HP give you a heart attack. You need only inflict 90 HP of damage to escape it. Hit it three times to accomplish this. You will then run away like the scared little bitch you are.

Just trade strikes with the Klikk. If Tidus gets two turns in a row, use the opportunity to heal yourself with a Potion. After a few turns, you'll receive some thoroughly unexpected help. WHen it's the gilr's turn, choose the Special command, then Use, and fire a Grenade at the Klikk. Have Tidus continue to attack, and the girl Steal. Let her use the Grenades she steals against the boss. You'll get a tiny bit of AP after the battle, and Tidus should gain a Sphere level. You'll also get two Ability Spheres and a bit of Gil.

Begin the fight by casting Cheer. Have Tidus attack and the girl use Grenades. When Tros moves out of attack range, access the Trigger Command Stand By. This will recover a small amount of HP. Tros will launch a powerful attack against you. Use Potions to heal yourself, then go back to attacking and using Grenades. When it runs away again, check Tidus's Trigger Command. You should be able to choose Pincer attack, which will allow both Tidus and Rikku to inflict more damage. (You may have to wait through another round of Nautilus Charge and Trigger Commands for this option to become available.) The Pincer Attack also prevents Tros from using the Nautilus Charge.

Use Cheer to reduce the damage you take from his attacks, and then pound on him with regular physical attacks. Try to avoid using healing items. After this fight, Tidus' HP and MP will be restored to full.

After destroying the first round of Sinscales, you'll be instructed to attack Sin itself. Thereafter, destroy two of the three Sinscales in front of you to reduce the damage you take, and focus on Sin. Use Kimahri's Lancet, Wakka's regular attack, and Lulu's Black Magic to defeat Sin, as you can only use long-range attacks. Swap in Yuna to heal, and Tidus to use Cheer. You should defeat it fairly easily.

This battle is just Tidus and Wakka. Use Cheer to improve your physical stats, and have Wakka use Dark Attack to keep you safe from the fiend's powerful attacks. Ignore the Sinscales. After using two Drain Touch attacks, Sinspawn Echuilles will strike with Blender, which can really damage you. Use Potions or Hi-Potions to recover HP, and don't forget to re-use Dark Attack when it wears off!

You should make an effort to have all of your party members in on this battle, since the AP reward is quite nice. Have Tidus cast Haste on Lulu, and then keep her in the party constantly casting Fire spells. Wakka should use Silence Attack to keep down the boss's spellcasting. Bring Yuna in to heal when necessary, and have Kimahri use physical attacks.

When the boss's HP drops below 2000, it will fall asleep. While sleeping, it regenerates HP, so attack it physically to wake it up. Once you do, though, it'll use the very nasty Earthquake attack. To avoid this, you might want to have Yuna summon Valefor and let him finish the battle, since Earthquake doesn't affect him.

Sinspawn Geneaux also has two tentacles. They have 450 HP each (inflict 500 or more damage to Overkill) and yield 5 AP each (7 if Overkilled). The tentacles absorb any magic cast on the body, so have Tidus Haste Lulu and then have her cast Fire on the tentacles repeatedly until they die. Kimahri should have a Piercing weapon equipped, so have him attack the body. Bring Yuna in to cast Cure and Esuna on poisoned characters; she can also summon Valefor if you'd like to try using Sonic Wings to delay Sinspawn Geneaux's turn. Have Wakka attack the tentacles. Once the tentacles are gone, the body unravels and you can start using normal attacks. Make sure you use Wakka's Silence Attack to prevent it from casting Water, and have Lulu keep casting Fire.
