A one-directional gloom covers the affected area, making the illumination level darkness. Creatures in the area can see outside of the affected area normally.
Creatures in the area have total concealment and can’t be located by sight. The shadow dispels all magical light sources of a lower spell level in the area and suppresses the effect of all light sources and light spells (including daylight). Creatures who cannot see in darkness move through the area as if they were blinded (generally, at half speed).
