The Koga Blade is a ninja sword in Final Fantasy XII. In the original version, its stats are the same as the Iga Blade besides the 1% difference in combo rate (where the Iga Blade is the better choice). In the Zodiac versions, the weapons are on more equal terms where the only difference is that the Koga Blade is Earth-elemental and the Iga Blade is Water-elemental. Despite this, the Iga Blade sells for more in the Zodiac versions where it was of equal price before.
Its license costs 45 LP in the original and 120 LP in the Zodiac versions, where it can be used by the Shikari. It is not possible to unlock all ninja sword licenses in the same board in the Zodiac versions. The player could forgo Ninja Swords 1 as Iga and Koga Blade are stronger and often obtained even earlier than the weaker ninja swords, or the player could choose between Iga and Koga as they have the same stats apart from the element. Earth is a rarer element than Water, so the player may want to go with Koga.
