Strongest of the scions created by the gods, they feared his growth, and so kept him a child. So indomitable is his strength that all things are by him twisted and pressed into oblivion. He alone fashions the laws governing all things, and administers punishment in place of the gods. So is he Keeper of Precepts, and his authority is absolute.

Talk to Geomancer Yugelu in Jaraha after the party aquires at least 10 Espers. Yugelu then unlocks the path within the Henne Mines that leads to Zodiark. This is a very difficult road, so be ready for the level 65 enemies and some of the nastiest battles yet!

Zodiark is an extremely powerful ally. Its powerful Scathe attacks can wipe out entire enemy clusters in seconds. Zodiark's final attack, Final Eclipse, requires that the summoner be under the stone effect. This is achieved by casting Break on the summoner either before or after Zodiark is summoned. Casting it on the summoner prior to summoning the Esper ensures that Zodiark immediately launches the Final Eclipse upon entering battle. This is especially effective when facing bosses. Final Eclipse causes approximately 50,000 HP of damage with each use.
