Sleep

Sleep is a spell of the enchantment school used by wizards and, formerly, bards and sorcerers as well. Sleep, as the name of the spell implies, places its target into a light slumber when cast successfully, overcoming the creature's willpower. The spell affects an area of roughly five feet in radius within a distance of 100 feet from the caster. Because of the complexity and energy involved in the spell, it can typically be cast only once per day. Creatures that manage to stave off the intended effects of the spell nonetheless find their body fatigued, slowing their movements and thought processes.

Prior to the Spellplague, bards and sorceresr also had access to the spell through the Weave, which could be cast more than once per day if the bard or sorcerer's energy allowed it or the wizard had prepared for such. Some druids or rangers used similar evocations, while a few clerics had access to a near identical prayer.
