“Each Uisge – The Drowned Tempest of the Fey Lochs” (Aughisky)

Each Uisge
Create

The Each Uisge is a Scottish fey shapeshifter, a predatory water horse that lures mortals to ride it before dragging them into its loch to be devoured—a spectral embodiment of beauty, deceit, and the hunger of the deep.

Appearance

The Each Uisge takes the form of a sleek, dark horse, its hide gleaming as if perpetually wet and its mane dripping with lakeweed. Its eyes shimmer with cold intelligence, betraying its malice beneath a mask of grace. When it walks among mortals, it assumes the shape of a captivating stranger—damp-haired, soft-voiced, and impossibly alluring, with an aura that both tempts and warns.

Behaviour

The Each Uisge hunts through deception, not pursuit. Patient and cruel, it lures travelers with false gentleness or the promise of companionship. Once its prey is close, the mask drops—its laughter turns to a scream, and its strength is monstrous. It delights in trust betrayed, savoring the fear that follows recognition.

Habitat

This creature haunts deep freshwater lochs and fog-veiled glens, venturing ashore only under cloud or moon. Its territory is solitary, sacred to its hunger; even lesser fey keep their distance, leaving offerings at the water’s edge to ward off its wrath.

Modus Operandi

Those who touch the Each Uisge find their hands fused to its slick hide, trapped as if caught in living tar. With a single bound, it plunges into the loch, dragging its victim into the abyss. Only the liver ever resurfaces—its cruel signature. In combat, the creature shifts seamlessly between forms, striking with hooves, jaws, or tendrils of liquid shadow.

Motivation

Driven by envy, hunger, and spite, the Each Uisge feeds on mortal flesh and the terror that seasons it. It covets the warmth and beauty of the living, destroying what it cannot possess. To this creature, every reflection upon the water is a reminder of what it will never be.

Shapechanger.

The Each Uisge can use its action to polymorph into a Medium or Large humanoid, a Large horse, or revert to its true form—a sleek, aquatic equine with eel-like features. Its statistics remain the same in each form. Equipment it carries transforms with it.

Amphibious.

The Each Uisge can breathe both air and water.

Adhesive Hide.

Any creature that touches or mounts the Each Uisge must succeed on a DC 16 Strength saving throw or become grappled (escape DC 16). While grappled in this way, the creature is restrained and dragged underwater if the Each Uisge enters water. When submerged, the creature begins holding its breath as normal.

Fey Glamour (3/Day).

As a bonus action, the Each Uisge radiates an aura of otherworldly allure. Each creature of its choice within 30 feet that can see it must succeed on a DC 15 Wisdom saving throw or be charmed for 1 minute. While charmed, a creature views the Each Uisge as a trusted companion and will approach within 10 feet if able. The effect ends if the Each Uisge attacks the creature or it enters water.


Actions

Multiattack.

The Each Uisge makes two attacks: one with its Bite and one with its Hooves, or two with Drowning Slam while underwater.

Bite (Horse or True Form Only).

Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 15 (2d10 + 4) piercing damage plus 7 (2d6) acid damage.

Hooves.

Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 13 (2d8 + 4) bludgeoning damage. The target must succeed on a DC 15 Strength saving throw or be knocked prone.

Drowning Slam (Underwater Only).

Melee Weapon Attack: +7 to hit, reach 5 ft., one target.
Hit: 18 (3d8 + 4) bludgeoning damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained and begins suffocating if it cannot breathe water.

Drag Beneath (Recharge 5–6).

The Each Uisge surges downward with one creature it has grappled. The target must make a DC 16 Strength saving throw or be pulled up to 30 feet deeper and take 21 (6d6) bludgeoning damage from the crushing pressure. The Each Uisge can release the target as a bonus action, leaving it drowning below.


Reactions

Reflexive Glamour.

When a creature targets the Each Uisge with an attack or spell, the Each Uisge can force that creature to make a DC 15 Wisdom saving throw. On a failed save, the creature becomes momentarily dazzled, granting the Each Uisge advantage on its next attack roll against that creature before the end of its next turn.


Legendary Actions

The Each Uisge can take 2 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. The Each Uisge regains spent legendary actions at the start of its turn.

  • Shift Form. The Each Uisge changes shape.
  • Fey Surge. The Each Uisge moves up to half its swim speed without provoking opportunity attacks.
  • Abyssal Drag (Costs 2 Actions). The Each Uisge pulls one grappled creature 20 feet deeper and deals 14 (4d6) bludgeoning damage.

Tactics

The Each Uisge hunts through deception and allure, often taking the form of a lost horse or alluring wanderer to draw prey near. Once touched or mounted, it triggers Adhesive Hide and Drag Beneath to drown its victims. In combat, it uses Fey Glamour to sow confusion, attacking from the depths before retreating into the murk. On land, it avoids prolonged battles, relying on ambush, charm, and terrain to maintain control.


Lore

“It smiles like a friend, it moves like a dream—and the moment you touch it, you’re already dead.”
—Tavish of the Glen, sole survivor of Loch Mourn

The Hungry Reflection.

Each Uisge (pronounced ekh oosh-ka) are ancient fey that dwell in deep lochs and highland tarns, born from the jealousy of drowned spirits. They envy mortal warmth and beauty, mimicking it through glamour and shapeshifting. To them, love and hunger are one—what they desire, they consume.

Mirror of Desire.

Each Uisge are master deceivers. In humanoid form, they appear as hauntingly beautiful strangers whose damp hair and glistening eyes betray their true nature. They prey upon those who long for companionship or wonder—artists, dreamers, and the lonely—drawing them into fatal embraces.

Claimers of the Loch.

A loch haunted by an Each Uisge becomes unnaturally still and mirrorlike. Local villagers may leave offerings of grain or silver at its edge to appease the “water horse.” Refusing these customs can invite tragedy—livestock vanish, and children’s laughter is replaced by ghostly neighs echoing across the night waters.

Fey Envy.

In the courts of the fey, Each Uisge are both feared and pitied. They are exiles, cast from the Seelie for their cruelty, too wild for even the Unseelie’s dark revels. Legends claim they were once river guardians cursed by love betrayed, forever hungering for the warmth they lost.

Hooks & Encounters.

  • Whispers from the Deep: Fisherfolk vanish on moonless nights, and silver coins appear on the shore, polished smooth as glass.
  • The False Rider: A pale traveler offers a noble steed to a desperate hero—but its eyes gleam too bright in the torchlight.
  • Broken Bargain: A druid circle seeks help banishing the spirit of a loch guardian twisted into an Each Uisge after its sacred pool was defiled.

Lair or Regional Effects (Optional; CR 9+ Each Uisge)

  • Waters within 1 mile grow unnaturally calm, reflecting fleeting faces of drowned victims.
  • Horses and beasts within 2 miles refuse to approach lakes or rivers.
  • Under moonlight, the loch echoes with phantom hoofbeats and faint, sorrowful song.

Treasure & Trinkets: Relics of the Drowned Fey

The Each Uisge rarely keeps treasure, but the depths it haunts are littered with what its victims once carried — and what the fey creature itself has claimed as tokens of its perverse affection. When an Each Uisge is slain or its lair explored, roll or choose from the table below.

d6Drowned Relic or Trinket
1A silver bridle engraved with shifting runes that shimmer like moonlight on water. If placed on a living horse, its mane turns black as ink until dawn.
2A mirror shard that reflects a different face — that of the last soul the Each Uisge drowned. Whispering to it in Sylvan causes faint ripples to appear across its surface.
3A waterlogged journal bound in eel-skin, its ink smeared into spiral sigils. When read under the full moon, it reveals the location of an ancient fey crossing.
4A silver coin worn smooth and cold, impossible to warm by touch. Tossing it into any still water makes ghostly hoofbeats echo from beneath.
5A string of river pearls, each containing the trapped whisper of a drowned voice. Crushing one releases a sorrowful wail audible for miles.
6A kelp-wrapped locket holding a single strand of dark hair and the faint scent of brine. Those who sleep with it nearby dream of a beautiful stranger standing in the shallows.

Treasure Note (DM Tip):
Each Uisge lairs typically contain 500–1,200 gp in mixed coinage, often coated in algae or fused with barnacles, plus one or two fey-related minor magical items such as Cloak of the Manta Ray, Potion of Water Breathing, or a cursed Ring of Swimming that pulls the wearer toward deep water.

SPECIAL ABILITIES

Adhesive Hide (Su)
Any creature that touches or mounts the Each Uisge must succeed at a DC 17 Reflex save or become stuck fast to its slick, glue-like skin. While the Each Uisge remains in water, this bond cannot be broken by physical means. A successful DC 17 Strength check or the application of freedom of movement ends the effect. The save DC is Charisma-based.

Aura of Allure (Su)
Creatures within 30 feet of an Each Uisge must succeed at a DC 17 Will save or be fascinated for 1 round whenever the fey surfaces from water or changes shape. This is a mind-affecting compulsion effect. The save DC is Charisma-based.

Drowning Drag (Ex)
When the Each Uisge has a creature adhered to it, it may dive underwater as a move action, dragging the victim beneath the surface. Each round the creature remains submerged, it must hold its breath or begin drowning as per the drowning rules. The Each Uisge releases its prey only when it ceases struggling—or when it wishes to toy with it again.

Fey Glamour (Su)
As a standard action, the Each Uisge may radiate a wave of beguiling beauty. All creatures within 30 feet must succeed at a DC 17 Will save or be charmed for 1 minute. Affected creatures perceive the Each Uisge as a trusted companion or perfect steed. This is a mind-affecting charm effect. The save DC is Charisma-based.

Change Shape (Su)
An Each Uisge can change shape into a Large horse, a Medium humanoid, or back to its true aquatic form as a standard action. This functions as alter self or beast shape II as appropriate, though the Each Uisge retains its natural attacks and abilities.

Fey Grace (Su)
The Each Uisge adds its Charisma modifier as a deflection bonus to its AC and as a bonus on all saving throws while in or touching water.

Water-Dependent (Ex)
An Each Uisge that remains out of water for more than 24 hours becomes weak and parched, taking 1d6 points of nonlethal damage per hour thereafter until immersed again.


TACTICS

Before Combat
The Each Uisge assumes the form of a friendly horse or a striking humanoid, using disguise self and its natural charm to lure travelers near the water’s edge.

During Combat
It opens with charm person or suggestion to coax a victim to touch or mount it, then triggers Adhesive Hide and dives into the depths, activating Drowning Drag. Against wary foes, it uses control water to isolate prey or deep slumber to disable stragglers.

Morale
If reduced below one-third hit points, the Each Uisge flees into deeper water, using control water to hinder pursuit. It never willingly leaves its lake or loch for long.


ECOLOGY & LORE

“It smiled like a friend and moved like a dream—and when we touched it, we were already dead.”
—Garran of Dunloch, final entry in his journal

Each Uisge (pronounced ekh oosh-ka) are malevolent fey shapeshifters that haunt lonely lochs and coastal shallows. They appear as magnificent steeds or alluring strangers to draw mortals near—only to drag them beneath the surface and drown them in icy silence.

Deceptive Beauty

In humanoid guise, an Each Uisge appears as a soaked, ethereal figure whose hair gleams with droplets of water and whose eyes reflect the moonlight like a mirror’s surface. In its true form, it is a sleek, dark water horse with eel-like musculature and a mane of writhing kelp.

Cursed Fey of the Deep

Legends claim Each Uisge were once river guardians who betrayed their oaths for mortal affection. As punishment, they were bound to the water and cursed to consume the life of those they love. Now, they embody both desire and death—the reflection of what mortals crave most, twisted into their doom.

Superstitions & Offerings

Villagers near cursed lakes leave silver coins or salted bread at dusk, hoping to appease the “water horse.” At night, faint hoofbeats echo across the surface, and sometimes a figure is seen weeping by the shore—its tears forming ripples that never fade.

Treasure

An Each Uisge’s lair is littered with the belongings of its victims—silver coins, tarnished jewelry, and corroded weapons. Typical treasure includes 500–1,200 gp in mixed coinage and 1–2 minor magical items tied to water or travel (cloak of the manta ray, ring of swimming, potion of water breathing).


Variant Each Uisge

In coastal or storm-lashed regions, an Each Uisge replaces control water with control weather (usable 1/day, CL 9th), manifesting as a roaring tempest when angered. These stormbound variants are known as Brine Horses, and their eyes glow with lightning beneath the waves.

But they must be ridden inland, for if they got so much as a glimpse of salt water they would gallop headlong away, carrying their riders with them, bear them deep into the sea and there devour them. It is said also that the untamed aughiska devours mortal cattle.

This monster’s normal form is that of an unusually attractive light horse. The water-horse is found near fresh-water lakes and rivers, where it wanders in search of its unsuspecting prey. Often people may attempt to capture and ride it, which it allows with some ease; however, the rider(s) soon discovers that the skin of the water-horse is sticky and one cannot pull loose easily.

If captured somehow and forced to serve as a (unridden) draft animal, the water-horse has the carrying capacity of a heavy horse. It will constantly attempt to kill its master, however, unless controlled by magical means.

Water-horses speak Common and their own language.

Combat

The water-horse will generally try to lure unsuspecting victims to its adhesive hide, and while they struggle to get free, the water-horse will run into the nearest body of water. Once submerged, the victim will begin to drown (see the Drowning Rule in the Dungeon Master’s Guide) unless freed. Water-horses are particularly hated and feared, because they seem to prefer to attack children, who are more careless than adults and are easier prey. A water-horse usually only uses its bestow curse ability if all other forms of attack fail against an opponent.

Adhesive (Ex) The skin of the water-horse is sticky, holding fast any creatures or items touching it. Any creature that touches a water-horse is stuck fast unless the creature succeeds on a DC 15 Reflex save. A successful DC 15 Strength check is needed to pry it off. A weapon that strikes a water-horse is also stuck fast unless the wielder succeeds on a DC 15 Reflex save. The check and save DCs are Constitution-based.

Spell-Like Abilities 1/day–bestow curse (DC 15).

Caster level 9th. The save DC is Charisma-based.

Amphibious (Ex) Although swater-horses are aquatic, they can survive indefinitely on land.

Change Shape (Su) A water-horse can assume the shape of any Small or Medium humanoid. In humanoid form, the water-horse loses its natural attacks. A water-horse can remain in its humanoid form until it chooses to assume a new one. A change in form cannot be dispelled, but a water-horse reverts to its natural form when killed. A true seeing spell or ability reveals its natural form.

Skills A water-horse has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line. A water-horse has a +4 racial bonus on Bluff and Disguise checks.

*When using its change shape ability, a water-horse gets an additional +10 circumstance bonus on Disguise checks.

Carrying Capacity A light load for a water-horse is up to 200 pounds; a medium load, 201-400 pounds; a heavy load, 401-600 pounds. A water-horse can drag 3,000 pounds.

ECOLOGY

Environment cold or temperate lakes and coastal lochs
Organization solitary (rarely pair)
Treasure standard plus one minor or medium water-themed magic item


SPECIAL ABILITIES

Adhesive Hide (Su)
As the base Each Uisge, but the DC increases to 19. While in water or rain, breaking free requires a DC 23 Strength check, or freedom of movement. A mythic creature may attempt this check as a free action once per round.


Aura of Allure (Su)
Creatures within 30 feet must succeed at a DC 19 Will save or be fascinated for 1d4 rounds whenever the Each Uisge surfaces, changes shape, or speaks. The aura intensifies in rainfall or mist, imposing a –2 penalty on saving throws. This is a mind-affecting charm effect.


Drowning Drag (Ex)
A mythic Each Uisge may drag an adhered creature underwater as a swift action by expending one use of mythic power. It can hold its breath indefinitely while submerged and may generate a 30-foot-radius vortex (as vortex, CL 10th) once per day.


Fey Glamour (Su)
As a standard action, the Each Uisge may radiate an overwhelming illusion of grace. All creatures within 30 feet must succeed at a DC 19 Will save or be charmed for 1 minute. Mythic foes that fail the save are instead confused for 1 round as they perceive drowning as rapture.


Stormbound Form (Su)
By expending one use of mythic power, the Each Uisge transforms into a living tempest for 1 minute. While in this form:

  • Gains fly speed 60 ft. (perfect)
  • Attacks deal an additional 2d6 electricity damage
  • Fog cloud surrounds it (10-ft. radius, moving with the creature)
  • Gains concealment (20%) in rain or mist
    This ability cannot be used outside of heavy rain, fog, or when partially submerged.

Fey Grace (Su)
As the base version, except the Each Uisge adds both its Charisma and Dexterity modifiers as a deflection bonus to AC and as a bonus on all saving throws while touching or immersed in water.


Mythic Resilience (Ex)
The Each Uisge can spend one use of mythic power to negate a critical hit or sneak attack. If it does so while submerged, it also heals 10 hit points.


Stormstride (Su)
Whenever the Each Uisge moves across or through water, it may leave behind a crackling trail of bioluminescent energy. Any creature attempting to follow directly behind it must succeed on a DC 18 Reflex save or be staggered for 1 round from the surging current.


TACTICS

Before Combat
The Each Uisge uses control weather or fog cloud to cloak the area, appearing as a phantom horse on the shoreline. It employs mass charm person to enthrall groups before striking.

During Combat
It opens with Fey Glamour, luring foes close, then grapples and submerges them using Drowning Drag. Against resistant enemies, it triggers Stormbound Form, summoning lightning and creating chaos among ranged attackers.

Morale
If reduced to 30 hit points or fewer, it uses greater invisibility and retreats beneath the waves, regenerating strength in the deep. It returns only to avenge desecration of its loch or offerings.


ECOLOGY & LORE

“When the loch wept thunder, we saw the water horse rise, wreathed in lightning and sorrow.”
—Ionn mac Brann, Stormseer of the Isles

Each Uisge of mythic power are ancient spirits of betrayal, once guardians of sacred waters who became living tempests. Unlike their lesser kin, they retain fragments of divine will, channeling storms as both punishment and expression.

They dwell in the deepest, storm-haunted lochs, guarding drowned relics or sealing away primordial evils. To summon one is to invite catastrophe—its appearance heralds floods, madness, and drowned souls.


Knowledge (nature or planes)

DCResult
19This is a mythic Each Uisge, a fey water spirit of devastating beauty and storm-borne wrath.
24It can transform into a tempest of water and lightning, dragging victims into the depths or through the air.
29Some mythic Each Uisge are cursed demigods, condemned to the loch until mortals invoke their name during a storm.

Treasure

A mythic Each Uisge’s lair holds treasure drawn from countless drowned ships—pearls, bronze relics, and the offerings of fearful villagers. Typical hoard includes 3,000–5,000 gp, 2–4 minor wondrous items, and one major water- or weather-themed item (helm of underwater action, trident of warning, or ring of storms).


Variant Mythic Each Uisge (CR 11 / MR 3)

Some legends speak of the White Mare of the Tempest, a radiant, spectral variant of the Each Uisge who emerges during full moons. It replaces control weather with tsunami (usable 1/day, CL 11th) and its Fey Glamour also causes hallucination (as weird) on creatures of CR 8 or lower.
