|Breath of Fire III Boss|
ガイスト Gaisuto (Geist)
Ryu and Garr meet up with Gaist at Cliff where they tell him they're trying to go and meet Myria (again, refered to as 'God') to get an explanation as to why the Brood had to be destroyed, but they need Deis' help to get there.
Gaist agrees to help them free Deis, but wants to talk to Ryu alone first, where he asks Ryu if he seriously wants to know the truth, and upon learning that Ryu does want to know the truth he then asks Ryu to fight him. After Gaist is defeated, he commends and apologizes to Ryu, and also says that he would've liked to go and meet God with them, but Deis' seal couldn't be broken as long as he is alive, and he crumbles into sand soon afterwards.
Gaist is fought with Ryu alone, so this fight may be slightly difficult. Gaist has Sanctuary, so Shield and any other buffs should only be used once or twice. Get rid of the torches as soon as possible, as they can heal Gaist or damage Ryu.
Gaist can use Howling, which can confuse Ryu, even if he's using Ascension. If the player chooses to use Ascension, choose Force + Frost to gain access to ice abilities. Use Frost Breath to get rid of the torches and use Focus in conjunction with Aura for maximum damage or Frost Claw each turn to defeat Gaist.
Another option is to use the Force + Fire + Thorn combination which increases Ryu's Attack Power and Agility and makes him to absorb fire attacks.
- As Gaist is a Devil-type foe a Demonbane in Ryu's hands (and in dragon form) will deal much more damage to him with normal attacks, making the use of the Frost Claw through the Frost Gene redundant. The blade can be acquired as early as possible in a developed Fairy Village through Exploration (Distant), at the time when you leave the Dauna Mines as a adult.
- If you want to deal the greatest amount of damage possible to Gaist (9999 Damage), use Gloom (25% success) in conjunction with 2x Focus and Aura as a Warrior. Gloom turns Gaist into a Undead with 0 Holy Resistance.
- Gaist's form for battle greatly resembles the Ifeleet from Breath of Fire II and slightly Deathevan. The latter resemblance may be at least somewhat intentional, as Deathevan is the spawn of Myria, who gave Gaist his powers, possibly hinting a connection.
- Upon defeating Gaist, examining his ashes immediately after the battle will allow the player to acquire the Beast Spear for Garr. This is the only way to obtain the Beast Spear.
