Monomi: Ichi is a Ninjutsu spell found in Final Fantasy XI. It may be learned by Ninja at level 25. When cast, the ability will consume one Sanjaku-Tenugui to prevent enemies from detecting the caster by sound. It does not prevent enemies with True Sound from detecting the player, nor does it prevent aggro from monsters that detect by sight. It has the same effect as the White Magic spell Sneak in Final Fantasy XI, but a different animation and a non-random duration. Additionally, the Ninjutsu version can only be cast on oneself. This spell was added in an update; there was originally no Ninjutsu version of Sneak. Square Enix has not added a Ni version of this spell yet.
