Corpselight

Corpselight was a necromantic spell with an alteration component that was generally known in Faerûn.

Effects
This spell caused a body, either dead or undead, to give off a faint radiance, from a thin nimbus outline to a full torch-like aura. The glow was spread out evenly over the corpse and did not flicker. This emanation was not harmful to the undead and could last for a few minutes to a few hours, depending on the level of the caster. The surface area of the corpse(s) was a limiting factor in how many corpses could be affected&mdash;many dead rats could be set aglow, or a couple of halfling zombies, or one elvish skeleton, for example. More experienced wizards could affect more and larger bodies. Not all forms of undead could be the target of this spell. Gaseous creatures like wraiths could be lit up, but ghosts could not.

Components
Verbal, somatic, and material components were required for this spell, including a corpse, a pinch of saltpeter, and a piece of a glowworm or a speck of phosphorus.
