Dokumori: Ichi is a Ninjutsu spell in Final Fantasy XI. It poisons an enemy. It is the least popular Ninjutsu spell in the game. With an unessential effect, a long casting time, and the fact that the player must use inventory space on Kodoku in order to cast this spell, it is rarely used. If Dokumori: Ni were available to players, providing a faster casting time, Dokumori may be a more popular spell. However, Dokumori: Ni cannot be cast bey players, and Dokumori: Ichi is currently rarely used by players. A testament to its unpopularity is that no one has tested it for its potency and recorded it.
