You create a shroud of darkness that prevents light from penetrating or emanating within the area. Light does not enter the area and any non-magical light sources, such as a torch or lantern, do not emanate any light while inside the area, even if their light radius would extend beyond the darkness. This also suppresses magical light of your darkness spell's rank or lower. Light can't pass through, so creatures in the area can't see outside. From outside, it appears as a globe of pure darkness.
Heightened (4th) Even creatures with darkvision (but not greater darkvision) can barely see through the darkness. They treat targets seen through the darkness as Concealed.
Traits
An action with this trait requires a degree of mental concentration and discipline.
Darkness effects extinguish non-magical light in the area, and can counteract less powerful magical light. You must usually target light magic with your darkness magic directly to counteract the light, but some darkness spells automatically attempt to counteract light.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
