Soporific is a Blue Magic spell learned from Flytraps in Final Fantasy XI. It puts all enemies within the area of effect asleep. This spell is roughly equivalent to Sleepga II, but is overwritten by many inferior sleep spells. Soporific costs 4 Blue Magic Points to set, and grants the stat changes HP-5 and MP+5 when set.

• This is one of Blue Mage's three Area of Effect sleep spells. The set includes:
  • Sheep Song
  • Soporific
  • Yawn

There are two main types of sleep in Final Fantasy XI: light-based sleep and dark-based sleep. Soporific inflicts dark-based sleep, just as the Black Magic spells Sleep, Sleep II, Sleepga, and Sleepga II do. Because dark-based sleep is more often used, Blue Mages will much more often set Sheep Song or Yawn instead of Soporific, because those inflict light-based sleep, thus giving the Blue Mages the ability to easily inflict sleep on monsters that resist the Black Mages' sleep spells. Usually, the only time a Blue Mage will set Soporific is in special situations where the Blue Mage will be putting many monsters to sleep, and could use more AoE sleep spells on separate recast timers.

• Blue Mages can set Soporific along with one of the following spells to create the Clear Mind combo.
  • Awful Eye
  • Corrosive Ooze
  • Feather Tickle
  • Filamented Hold
  • Lowing
  • Maelstrom
  • Mind Blast
  • Poison Breath
  • Sandspray
  • Venom Shell
  • Warm-Up

Note: Unlike other job traits obtainable by Blue Mages, the effect stacks for each pair in this group. Each set gives the next tier of Clear Mind for an additional MP Recovered While Healing + 3 effect. A maximum of Clear Mind IV can be achieved granting a max bonus of MP Recovered While Healing +12. Clear Mind V is not attainable.
