Sleep was a spell of the enchantment school used by wizards, bards and sorcerers, as well as warlocks with Archfey patrons. The spell was also used by some clerics of the derro god Diirinka and the elven goddess Sehanine Moonbow.
Sleep, as the name of the spell implies, placed its targets into a light slumber when cast successfully, overcoming the creatures' willpower. It affected a number of creatures that depended on the caster's power.
Between the Spellplague and the Second Sundering, because of the complexity and energy involved in the spell, it could typically be cast only once per day and affected an area of roughly five feet in radius within a distance of 100 feet from the caster. Creatures that managed to stave off the intended effects of the spell nonetheless found their body fatigued, slowing their movements and thought processes.
The spell needed verbal, somatic and material components to be cast. The materials required were either a pinch of fine sand, rose petals or a cricket, any of which could be replaced by the use of an arcane focus.
Prior to the Spellplague and after the Second Sundering, bards and sorcerers 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.
