Atheist

From Final Fantasy Wiki

The Atheist status effect, as shown on Construct 8, in comparison to the Faith status on the Mystic.

Atheist, also known as Innocent, is a status effect in Final Fantasy Tactics. A character affected by Atheist loses all faith in the gods, and their Faith will fall to zero, making magic attacks useless on that character. Adversely, that character thus cannot use magick. Nether Mantra also will not work on the character, rendering zero damage.

Atheist is granted by using the Mystic's Disbelief, the Templar's Doubt, and by the weapon Gokuu Pole. Automatons such as Construct 8 have permanent Atheist status.
