Banshees have demonstrated a wide range of powers, which seems to suggest that, while some powers are common among Banshees, they still each use the supernatural energy that flows through them in different ways, causing them to have unique power sets. However, many of these powers can also be taught by one Banshee to another, suggesting that there is potential for a Banshee to have every power but it is an extremely rare occurrence.
Death Sense: As harbingers of death, Banshees can sense when someone has died or is about to die. This is usually accompanied by a trance-like state that draws the Banshee to the location of someone who has recently died or who is near-death, though, with experience and training, the Banshee can learn to remain somewhat conscious during this event.
Clairaudience: The ears of a Banshee are naturally tuned to levels of the universe that only they can hear. This gives them an ability to discern details of a person's death (or impending death) through the sounds they can perceive which no one else can. These sounds can include voices (such as whispering or screaming), gunshots, electricity, buzzing, growling, fighting, etc.
Enhanced Hearing: While Banshees do not have a sense of hearing that is as heightened as a Lycan or other species, which is said to be 100 times more powerful than that of a human, Banshees do seem to possess hearing that is slightly more powerful than their human counterparts.
Premonitions: Banshees possess the power to experience premonitions that allow them to sense a person's death, which usually allow them to discern how a person dies, where they die, and/or what will cause the death in the first place. This power is most often used as an extension of their power of clairaudience, as the supernatural phenomena that they can sense with their enhanced hearing can take the form of auditory premonitions of an impending death. However, as a Banshee's powers grow, their premonitions evolve from being purely auditory to often being visual as well; making it easier for them to interpret what their premonition is trying to tell them. However premonitions are not always literal and can often be up for interpretation, especially given the fact that the premonitions do not typically include every single detail of a person's death.
Astral Premonitions: In some cases, a Banshee's power of premonition can advance to the point where they can astral project themselves into their visual premonitions, allowing them to pause and examine the details of the vision as well as interact within it
Divination: Banshees are often mistaken for and compared to psychics, due in part to their ability to use various forms of divination as a tool to gain information about the death and danger they are foretelling. There are a wide variety of means through which a Banshee can use divination, many of which also involve the use of their other powers, such as clairaudience. The forms of divination used by Banshees on the series include:
Sound Divination: Using their power of clairaudience, some Banshees can divine for information by using sound vibrations to trigger their ability to perceive supernatural energy.
Psychometry: Some Banshees have the ability to discern information about a person's death by making physical contact with a person or with an object belonging to the person in question. The absence of any kind of divination can also give a Banshee some idea of what is going on for example; if a banshee is to come across the scene of an accident where there is a lot of blood but no bodies, if they were to touch an object in the vicinity that is directly linked to the accident and see’s nothing, then it is likely the parties involved in the accident are still alive.
Automatic Writing: Some Banshees are able to gain information by going into a trance-like state and freely writing without conscious thought or awareness.
Harbinger Connection: All Banshees possess an almost psychic or telepathic connection to each other, which they can use to communicate with one another, regardless of how far away they are. However, this is an advanced Banshee power that needs to be consciously activated to use it; it is easier to utilize this ability if the harbingers in question already have an established relationship, such as being friends or allies.
Banshee Connection: The harbinger connection can be frequently used in order to communicate they can't be physically in the same place. For an example, this ability can be used to teach other Banshee’s in order to escape from a bad situation
Banshee Scream: A Banshee's most important and valuable power is their voice, which they can use to achieve various effects when wailing or screaming. This is a power that all Banshees possess, though some of the specific aspects and applications of this power often need to be consciously learned before the Banshee can use them effectively.
Death Announcement: When a Banshee has either received a premonition that indicates that someone has died or will die shortly, or when they have just come out of a fugue state to find that they have located a recently-deceased body, a Banshee will scream at the top of her lungs, both as a sort of lament for the dead as well as an alert to others that a death has occurred. This is almost always an unconscious or instinctual reaction to death and not something that the Banshee can actively control.
Premonition Enhancement: A Banshee's scream can also be used to enhance their power of Clairaudience and auditory premonitions by clearing out ambient noises from their ears so that they can focus only on the auditory aspects of the premonition they are receiving.
Concussive Scream: The most powerful use of a Banshee's scream or wail is as an offensive weapon, though this, too, is an advanced Banshee power that often (but not always) requires experience and training to use. When a Banshee's wail is given both focus and direction, it can produce so much power and force that it can shatter glass, overload electronics, shatter skulls and eardrums, and even create concussive blasts strong enough to throw grown men across a room.This power can be focused further by the Banshee channeling their scream through their hands to push people and other objects backward. However, Banshee does not need to emit a full scream for their voice to affect their environment; simply speaking in a highly emotional state, regardless of the volume and pitch, can cause objects to shake and disorient people around them, especially if said Banshee is powerful or experienced enough.
Supernatural Immunity: Since Banshees are humans who access the supernatural rather than fully supernatural creatures who are ruled by mystical forces, Banshees are immune to the effects of many supernatural phenomena. A bite from an Alpha Werewolf will neither kill them nor turn them, provided the wounds from the bite aren't fatal
Supernatural Sensitivity: Banshees, as conduits of supernatural forces, can sense, seek out, and identify its energy, though how they are able to do this varies among individuals.
