Ultimate Weapons
Helpful Hint
Helpful Hint
Note that all weapons can be upgraded twice. For the first upgrade, they will involve into a new weapon. For example, an 
Axis Blade will upgrade into an Enkindler. They can then be upgraded a second time into a character’s ultimate weapon and this ultimate weapon is the same no matter which weapon you evolve. Check out the Upgrading Equipment page in the Tips and Tricks section for more information.
The ultimate weapon form will have the same Passive Abilities as the weapon that was upgraded. For example, Enkindler has the 
Attack: ATB Charge II passive ability, so if is upgraded into the Omega Weapon, the Omega Weapon will also have the same passive ability.
