The caster creates an
area of total
darkness. The
darkness is impenetrable to normal
vision and
darkvision, but the caster can see normally within the blacklit
area. Creatures outside the spell's
area, even the caster, cannot see through it.
The spell can be cast on a point in space, but the effect is stationary cast on a mobile object. A character can cast the spell on a creature, and the effect then radiates from the creature and moves as it moves. Unattended objects and points in space do not get
saving throws or benefit from
spell resistance.
