Atheist (イノセン, Inosen?), 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 used by that character ineffective. Additionally, all magic cast on that character will have no effect at all. Nether Mantra also will not work on the character, rendering zero damage. Atheist lasts for 32 ticks.
Atheist is granted by using the Mystic's Disbelief, the Templar's Doubt, and by the weapon Gokuu Pole. Automatons such as Construct 7 and Construct 8 have permanent Atheist status. Note that Atheist is only a temporary status effect, by using the Orator's Speechcraft, Enlighten to lower the target's Faith will have permanent effect, though this can be adjusted by another Speechcraft skill, Preach.
