Night

Night (夜, Yoru) is a Blue Magic spell. It inflicts the Sleep status ailment on all units, enemy and ally, except the caster.

Final Fantasy IX
Night is learned by Quina and has a 100% accuracy, meaning it will put all targets to sleep if they are not immune to the status. It is commonly used when the party has Insomniac equipped to block Sleep. It costs 14 MP to cast and can be learned by eating a Nymph, Abomination, Seeker Bat, or Grimlock.

Final Fantasy Tactics Advance
Night is learned from Lamia-type enemies. A common strategy with this move is to equip Fortune Rings to block Sleep.

Final Fantasy Tactics A2: Grimoire of the Rift
Like Final Fantasy Tactics Advance before it, Night is learned from Lamias.
