Shadow evocation

Shadow evocation, formerly known as shadow magic (but not to be confused with the general field of shadow magic ), was an illusion spell that drew energy from the Plane of Shadow in order to create a semi-real duplicate of any evocation spell of lesser power. If the victim recognized the illusion, the shadow energy was a lot less effective than the duplicated spell.

Components
Shadow evocation used verbal and somatic components only.

History
The spell was introduced in 3266 NY (−593 DR) by Netherese arcanist and researcher into the planes, Shadow, under the name Shadow's magic, later simplified to shadow magic or shadow evocation.

Shadow evocation was an uncommon spell in Faerûn in the 1360s DR; in Zakhara it was also known but rarely, though exceptions like the assassins and sorcerers of the Jaezred Chaulssin for whom the spell was a common part of the magical arsenal existed.
