Vaan using Horology.

Horology (時間攻撃, Jikan Kōgeki?) is a technick in Final Fantasy XII that uses the game clock's minute to deal damage on targets within a radius around the selected target.

This is done according to the formula:

In the Zodiac versions it is:

In which is the user's level and is the second digit in the game clock's minute. Due to the nature of the formula, damage dealt from using Horology caps at 4,009 HP (8,019 HP in Zodiac versions) (). The attack rarely misses and can be used multiple times within the minute. If used on multiple enemies, it will always hit one of them, even if blinded.

Horology's damage is actually determined at the moment the damage is inflicted. Even if the caster starts readying it during XX:47:55 and the damage is inflicted during XX:48:02, its damage is calculated during the damage. So, the damage calculation is:

instead of

Exploiting Horology is made simple by pausing during its charge time via the party menu. Once the second digit of minutes reaches nine, Horology's potency will be at its peak. However, using it consecutively can be tedious.

In the Zodiac versions, this technick can be used by three job classes: Machinist, Time Battlemage and Foebreaker, although Foebreaker must acquire the Esper Belias license first.

In the Zodiac versions, Horology can be bought from shops after the party returns from the Leviathan. In the original, it is available slightly earlier, from the technick shop in Bhujerba. It is also a treasure in the Trial Mode Stage 22 with Diamond Armlet.


Horology is the art or science of measuring time. Clocks, watches, clockwork, sundials, clepsydras, timers, time recorders and marine chronometers are all examples of instruments used to measure time.
