Darkness

Darkness removes all illumination from one or more areas. It hides creatures and objects inside, but it is not an opaque wall: lights and illuminated places beyond the area remain visible. A creature needs Darkvision or another suitable sense to perceive something left without light (see 4).

A successful Dispel Magic ends Darkness. Light can also oppose it; Light gains +10% on the caster level check. Dispelling one connected area removes the entire casting.
