A dim gray haze appears around the creature. Light bends around this haze, leaving the creature in a patch of strange and shifting darkness.
Cloak of dark power creates a dusky haze around the subject. The haze does not interfere with vision, but the subject and anything it wears or carries is protected from the effects of full sunlight, even under the open, daytime sky of the surface world. A drow subject suffers no blindness or bright illumination combat penalties while under the effect of cloak of dark power.
