Weather Control: Able to sense weather changes and bend all aspects of it on a whim. Their area of control, however, is rather limited as they are only able to manipulate the immediate surroundings. Changes may be as little as temperature fluctuation to calling upon harsh storms.

---

Frostwave: A powerful connection to the water allows them to call upon it in both its liquid and solid forms. The chilling bite of ice and the flowing current of water itself.

---

Cleansing Water: Capable of healing both minor and extensive wounds with a specialized variant of water magic. With concentrated efforts it is rumored that the muirinn are even capable of regeneration though not without a heavy cost. They spark fever and crippling exhaustion, and are often bedridden for days at a time after each session to regain themselves; leaving them extremely vulnerable.
Ill affects may be lessened and shared between muirinn if they are working together to heal a single target.

---

Clairvoyance: May perceive sights and sensations outside of their natural vision. Gaining glimpses of the past, present, and future. Whether these events are of their realm or an alternative reality is rarely known.

---

Aquatic Communication: Commune with sea beasts through telepathy or animalistic vocalizations. Any aquatic species may be spoken with and understood.

---

Depths Embrace: Extremely sticky adhesives can be secreted from their body, acting as glue to capture their prey as well as allow them to stick to objects.

---

Vocal Manipulation: Captivating and seductive, their enchanting song is capable of luring nearly any who hears it into their embrace, a mind easily falling under their control. Those more in tune with such abilities may even cast such enrapturement through their gaze. A sharp contrast to their alluring voice, they may emit a highly amplified shriek in a destructive blast of sound.

---

Enhanced Senses: Heightened ability to see, hear, and smell on levels that far surpass what a human is capable of. Due to their heightened senses, they are able to see in the dark as if the entire area was cast in dim light.

---

Blind Spot: Their natural field of view encompasses all directions except directly behind them. In order to behold this single blind spot, they must turn their head.

---

Mystical Beauty: Possesses a supernatural beauty within their humanoid form that grants them a mystical, otherworldly appearance. To many, they are physically appealing as if a gaze is twisted into seeing the muirinn in an idealized form of beauty.

---

Frigid Immunity: Unharmed by natural cold and water pressure, they can dive to extreme depths. Frigid habitats do not lower their body temperature and they can exist within such climates with little to no clothing or protection.

---

Water Dweller: These creatures possess both lungs and gill structures allowing them to breathe both on land and beneath the water. When beneath the water's surface, they have augmented speed making them swim faster than any race.

---

Ripples Perception: Perceive the movement of water, the flow of its currents and any disturbances within. Can easily determine the size and location of threats in aquatic environments.

---

Aquatic Shape: When in possession of their skin (selkie) or bridle (kelpie), the muirinn may freely turn between their aquatic and mortal visage. However, their treasured possession must be completely removed to fully walk on land.

---

Call of the Water: When not in the water they suffer from a constant call to return to it. Prolonged separation from their chosen body of water can be horribly depressing to the muirinn. This desperate urge may be lessened by keeping a vial of either sea or fresh water on their person.

---

Iron: Prolonged exposure drains their energy and weakens them while contact with anything made of iron burns the skin and causes agonizing pain.
For any looking to destroy a muirinn’s prized treasure (skin or bridle), cold iron is one of the only materials capable of damaging it.

---

Prized Possession: The muirinn’s treasure (skin for selkies and the bridle for kelpies), contains their glamour and grants them access to the watery depths. Should their possession ever be stolen away they will lose access to such abilities and be unable to return beneath the waves until it is regained. If their possession is ever completely destroyed their fae self will die, however, there is a slim chance that their human self may survive.

---

Delectable: The radiating scent of a muirinn triggers a greater impulse for their fellow supernatural to try consuming them. Werewolves and vampires alike find their flesh and blood especially delicious, literally good enough to eat. To combat the adhesive properties of the muirinn's flesh, the saliva of werewolves - and to a lesser extent vampires - will steadily dissolve their bonds.

---

Magic: Muirinn are susceptible to injury from all manners of magic.

---

Ash Wood: Simply burning the wood repels and wards away those of ill or evil intent, while if any trick a muirinn into consuming the ash wood’s ashes it acts as a debilitating poison.

---

Warding Ash: Burning the primary vegetation of a muirinn’s habit - often times kelp or seagrass - and collecting the ashes has become a habitual practice amongst the superstitious. Ashes placed upon the threshold of a building prevent beasts from following one home while consuming the ashes or keeping it on their person may allow them to escape a monster’s charms.

---

Adder Stone: So long as the muirinn is wearing their treasured item, peering through the hole of an adder stone allows one a glimpse past their alluring disguise. Humanoid visage melting away to reveal the true nature of a beast.
