This spell is similar to a continual light or continual darkness spell, except it creates an area of perpetual shadow and gloom and lasts until negated by magical light, magical darkness, or a dispel magic spell. Creatures with penalties or bonuses in areas of shadow implement them in this spell's effects. As with the continual light and continual darkness spells, this spell can be cast into the air, onto an object, or at a creature . In the third case, the continual shadow affects the space about 1 foot behind a creature that successfully rolls its saving throw vs. spell; a failed saving throw means the continual shadow is centered on the creature and moves as it moves. If the spell is cast on a small object that is then placed in a light -proof covering, the spell effects are blocked until the covering is removed.
Continual shadow brought into an area of magical darkness or magical light cancels the light or darkness so that otherwise prevailing light conditions exist in the overlapping areas of effect. A direct casting of a continual shadow spell against a similar or weaker magical light or magical darkness cancels both.
This spell eventually consumes the material it is cast upon, but the process takes far longer than the time in a typical campaign . Extremely hard and expensive materials might last hundreds or even thousands of years.
Notes: Granted by the Chultan god Eshowdow of the Forgotten Realms setting.
