Judgment Blade(不動無明剣, Fudō Mumyō Ken?, lit. Unmoving Lightless Sword), also known as Stasis Sword, is a recurring ability in the series, primarily found in the Ivalice series. Despite being an ability usable by a few characters, it is generally associated with Agrias Oaks.
Judgment Blade is an ability usable by the Holy Knight, Rune Knight, and Sword Saint. It requires 100 JP to learn, has a range and effect of 2, and activates immediately upon use. It is Holy-elemental (but, by a bug, uses the element of the weapon) and can inflict Stop. The user must have a sword equipped in order to use the ability.
