Kurayami: Ni is a Ninjutsu spell in Final Fantasy XI that blinds a single enemy. The blindness from this particular spell reduces an enemy's accuracy by 30. This spell is the higher-level version of the spell Kurayami: Ichi. It costs 1 Sairui-ran tool to cast. The the minimum blindness effect of the Black Magic spell Blind II is only half as powerful as this Ninjutsu spell (Blind II lowers an enemy's accuracy by 15 at minimum; the maximum is unknown). Blind II will not overwrite this spell's blind effect, suggesting that this spell might be stronger than Blind II can be.
