Stygian Blackness (3.5e Spell)

This spell creates an opaque, oily black cloud in a 40-foot radius centered on a point in space which blocks all light. All creatures within the cloud can detect the stench of blood and sulphur, and hear faint whispering of silibant voices. Non-evil creatures within the cloud have their sight completely obscured by the darkness. At the time of casting, the caster may designate a number of non-good allies to be exempt from the spell's blinding effect, up to his caster level.

Stygian Blackness dispels any Light spell of equal or lower level.

Material Component: a pinch of sulphur and a drop of oil mixed with blood
