This battle is fought with Galuf alone. It is scripted, so Galuf cannot die during the battle, even when his HP goes down to 0. It is impossible to lose unless the player intentionally makes Galuf zombify or petrify himself. The Blue Magic spell Self-Destruct will also work to end the battle.
In the SNES version, if the player uses the Kiss of Blessing mix on Exdeath during the battle, the game will be bugged and the battle can never end.
This battle is fairly tough, as Exdeath occasionally inflicts Condemn on a party member, giving them 30 seconds before death. Exdeath's Dynamo rearranges the party's row positions. Exdeath will use Firaga and Blizzaga in succession.
Fallen characters should be revived immediately, and the party should use strong attacks and summonGolem. The party can throw the Excalipoor at Exdeath, which will deal about 3,500 HP of damage. He is vulnerable to Level 2 Old, which slows him down and reduces his damage over time.
If Exdeath reverses the party's row with Dynamo it is best to switch back to the original rows. The strategy should also include Staves of Light so the party can cast Holy for over 2,000 damage for every staff the party has. If the player has not already obtained the staves, it is recommended to return to Ghido's Cave and fight Metamorphs until they drop some.
Exdeath uses Blizzaga and Firaga in succession, but if the player has the Ice Shield (or Aegis Shield) his Firaga attack will be useless, as the character will have absorbed the Blizzaga attack. This means as much as 1,600 HP can be absorbed from Exdeath each round.
