Traits

Amphibious. Iku-Turso can breathe both air and water.

Primordial Regeneration. If Iku-Turso begins its turn in water, it regains 60 hit points. If reduced to 0 hit points, it dissolves into a storm of brine and lightning, reforming after 1d10 days unless destroyed by divine intervention.

Abyssal Majesty. Any creature that starts its turn within 120 feet of Iku-Turso must succeed on a DC 26 Wisdom saving throw or be frightened until the start of its next turn. Creatures who succeed are immune for 24 hours.

Mythic Resilience (Recharges after a Long Rest). When Iku-Turso is first reduced to 0 hit points, it does not die or fall unconscious. Instead, it roars, triggering its Mythic Awakening, restoring 600 hit points and unleashing a second phase.

---

Innate Spellcasting.

Iku-Turso’s innate spellcasting ability is Charisma (spell save DC 26). It can innately cast the following spells, requiring no material components:

At will: control water, lightning bolt, detect thoughts, darkness
3/day each: maelstrom, cone of cold, blight, wall of force
1/day each: tsunami, storm of vengeance, power word kill

---

Actions

Multiattack. Iku-Turso makes three attacks: one with its Bite and two with its Tentacles.

Bite. Melee Weapon Attack: +20 to hit, reach 30 ft., one target. Hit: 80 (10d12 + 14) piercing damage plus 27 (6d8) cold damage.

Tentacle. Melee Weapon Attack: +20 to hit, reach 60 ft., one target. Hit: 72 (8d12 + 14) bludgeoning damage, and the target is grappled (escape DC 26). Until this grapple ends, the target is restrained.

Abyssal Tempest (Recharge 5–6). Iku-Turso summons a cataclysmic storm in a 300-foot radius centered on itself. Each creature of its choice in that area must make a DC 26 Constitution saving throw, taking 144 (24d12) cold damage and 72 (12d12) lightning damage on a failed save, or half as much on a success. The area becomes difficult terrain, and visibility is reduced to 10 feet for 1 minute.

---

Legendary Actions

Iku-Turso can take 3 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.

• Tentacle Slam. Iku-Turso makes one Tentacle attack.
• Fathom’s Grasp (Costs 2 Actions). Iku-Turso pulls all creatures within 120 feet up to 30 feet closer to it.
• Thunderous Roar (Costs 3 Actions). Iku-Turso unleashes a roar that echoes across the sea. Each creature of its choice within 240 feet must succeed on a DC 26 Constitution saving throw or be deafened and knocked prone.

---

Mythic Actions (Phase II)

While in its Mythic Form, Iku-Turso can use the following actions in addition to its normal legendary actions:

• Abyssal Rebirth. Iku-Turso calls forth fragments of its drowned essence. Three Abyssal Spawn (use kraken priest statistics) rise from the water to serve it.
• Tidal Annihilation (Costs 3 Actions). Massive waves sweep the battlefield. All structures within 1 mile take 200 bludgeoning damage; creatures must succeed on a DC 26 Strength saving throw or be swept 100 feet and knocked prone.
• Sea of Eyes (1/Rest). The water around Iku-Turso becomes sentient and malevolent for 1 minute. Any creature that ends its turn in water within 300 feet must succeed on a DC 26 Wisdom saving throw or be paralyzed by terror.

---

Lair Actions

When fighting inside its lair, Iku-Turso can invoke the sea itself to act on its behalf. On initiative count 20 (losing initiative ties), it takes one lair action to cause one of the following effects:

• Boiling geysers erupt from the sea floor. Each creature within 120 feet must make a DC 24 Dexterity saving throw or take 45 (10d8) fire damage.
• A colossal current surges. All non-aquatic creatures must succeed on a DC 24 Strength saving throw or be moved 60 feet in a direction of Iku-Turso’s choice.
• Dark, psychic whispers echo through the deep. Each creature that isn’t a construct or undead must succeed on a DC 24 Wisdom saving throw or be charmed until initiative count 20 on the next round.

---

Regional Effects

The region containing Iku-Turso’s lair becomes twisted by its abyssal presence, which creates one or more of the following effects:

• Endless Storms. Within 100 miles of its lair, the sea is perpetually stormy, and navigation checks are made at disadvantage.
• Whispers of the Deep. Dreams and thoughts of nearby mortals are haunted by visions of drowning and monstrous eyes beneath the waves.
• Blighted Sea Life. Aquatic creatures within 50 miles become aggressive, diseased, and unnaturally large.

If Iku-Turso dies, these effects fade over 1d10 days.

---

Combat Tactics

Iku-Turso begins combat by summoning a storm with Abyssal Tempest, controlling the battlefield with waves and darkness. It targets spellcasters first, grappling them with its tentacles to drag them beneath the sea. In its mythic phase, it floods the area, calling forth abyssal spawn and using Tidal Annihilation to reshape the terrain. Victory against Iku-Turso requires more than strength—it demands defiance against the ocean itself.

Iku-Turso, The Eternal Terror of the North
The Drowned God of Vengeance and Storms

Born from the primordial chaos before the world took shape, Iku-Turso is the ocean’s wrath made flesh—a monstrous, antediluvian god whose name was once whispered by sailors and shamans alike in trembling awe.

Said to dwell in the blackest trenches of the northern sea, his many-eyed visage and tangled beard of kelp mark him as both divine and abhorrent. From his slumber rise plagues, tempests, and omens of war; even the gods of men once feared his surfacing. Legends claim his breath kindled the first storms and his blood seeded the sea with monsters. When he stirs, coastlines crumble and nations drown beneath the tide.

To face Iku-Turso is to defy inevitability—to challenge the endless cycle of decay and renewal that the deep itself demands. Few mortals have seen him and lived; fewer still can bear the knowledge of what waits beneath the waves when the Eternal Terror awakens once more.

Iku-Turso

Source: Pathfinder d20pfsrd.com

This grotesque, emerald-scaled creature resembles a crossbreed of an eel, a viperfish, and a clawed humanoid.

Iku-Turso are malevolent sea monsters living in seas around Pohjola the home of all evil.

Iku-tursos are hideous denizens of the deep sea. There, they venerate the sinister Kiputytto Lady of Poison, god of plague and contagion and Loviatar God of torment. Theres victims are plucked from ship and shore in special air-filled torture chambers. Disease is sacred to the iku-tursos, and those who suffer from sickness are considered blessed -an iku-turso often chooses to leave obviously diseased victims to their fates rather than attempt to capture them.

SPECIAL ABILITIES

Disease (Su) An iku-turso’s bite inflicts a strange, supernatural disease called tursas. This disease causes the victim’s skin to grow painfully scaly, causes strange hallucinations, and eventually transforms the victim into an iku-turso. Tursas: Bite—injury; save Fort DC 20; onset 1 minute; frequency 1/day; effect 1d3 Wisdomdamage and 1d6 Charismadrain; cure 2 consecutive saves. As long as a victim suffers any ability damage from tursas, it gains the ability to breathe water. A creature reduced to 0 Charisma by this disease transforms into a fully grown and healthy iku-turso—it immediately forgets its previous life and abilities and seeks out the nearest iku-turso community to join it. A wish or miracle can reverse this transformation. The save DC is Constitution-based. Light Lure (Su) As a standard action, an iku-turso can call forth a few small points oflight, functioning like a dancing lights spell (CL equals the iku-turso’s HD) except as described here. Creatures within 100 feet of one of these lights must make a DC 18 Will save upon sighting them or be compelled to approach them by the safest and most direct path. A creature that successfully saves is immune to the same iku-turso’s light lure for 24 hours. If a subject of this effect has to move through hazardous terrain to reach the lights, that subject receives another saving throw to end the effect before entering the hazardous terrain. This effect ends once the character reaches the light or takes any form of damage. This is a visual mind-affecting charm effect. The save DC is Charisma-based.

Crushing Depths (Recharge 5–6).

Devour the Deep (Mythic Form Only).
The Doom-Turso inhales a vortex of water and souls. All creatures of its choice within 100 ft. must succeed on a DC 21 Strength save or be pulled 30 ft. toward it and take 70 (20d6) necrotic damage.

---

Legendary Actions

The Doom-Turso can take 3 legendary actions, choosing from the options below. Only one may be used at a time and only at the end of another creature’s turn.

• Tentacle Swipe. Makes one Tentacle attack.
• Thunderous Roar (Costs 2 Actions). All creatures within 60 ft. must succeed on a DC 21 Wisdom saving throw or be frightened until the end of their next turn.

• Corpses left in the water rise as Drowned-Turso within 24 hours.

These effects fade 1d10 days after its death.

---

Tactics

The Doom-Turso strikes first from beneath the waves, using Crushing Depths to disable groups of foes before surfacing to grapple spellcasters and ranged attackers. It creates isolation with storms and maelstroms, then focuses on survivors. When bloodied, it shifts to Mythic Form, transforming the battlefield into a living tempest and annihilating all that oppose it. It fights relentlessly, leaving only a black whirlpool in its wake.

---

Lore & Role

When black tides churn and storm clouds blot out the stars, sailors whisper the name Doom-Turso, the Cataclysm of the Deep. Born from the abyssal womb of Iku-Turso, this living storm is both child and echo of the ancient terror. It surfaces only when the sea hungers for ruin, heralding drowned kingdoms and shattered coasts. To behold it is to witness the ocean’s hate made flesh — a god’s nightmare loosed upon the mortal world.

---

Appearance

The Doom-Turso towers like a mountain of sinew and coral-encrusted armor, its form half-whale, half-kraken, and wholly unnatural. Barnacle-spined tentacles coil from its back like living storms, crackling with pale lightning beneath translucent, bioluminescent skin. Its elongated head bears abyssal sun–like eyes and a jaw lined with obsidian teeth large enough to bite through ship hulls. Its massive body displaces water in a 60-foot radius, creating waves that batter anything nearby.

Storm-Turso

Huge monstrosity (sea spawn), chaotic evil

---

Lore & Role

The Storm-Turso is the herald of Iku-Turso’s wrath, a semi-divine spawn that prowls the ocean depths to scout, strike, and command lesser servants of the deep. Coastal communities fear its sudden appearance, for wherever it rises, lightning splits the sky, waves rise to engulf ships, and the sea seems alive with malicious intent. It acts as the lieutenant of Doom-Turso, preparing the battlefield for the cataclysmic arrival of its greater sibling.

• Summon Drowned-Turso. One Drowned-Turso appears under Storm-Turso’s control.

---

Tactics

Storm-Turso begins combat by using Crashing Wave and Thunderclap to scatter and weaken enemy formations. It grapples key targets with its tentacles, then uses lightning attacks to disrupt spellcasters. It commands Drowned-Turso to flank and harass, forcing the party into water hazards. Storm-Turso prefers ambushes near reefs, sunken ships, or storm-heavy seas.

---

Physical Description

Storm-Turso is roughly 45 feet long, with a sinuous, coral-encrusted body and barnacle-spined tentacles. Electric arcs flash along its bioluminescent spines, and its glowing pale blue eyes exude intelligence and malice. Its gaping maw reveals jagged obsidian teeth capable of splitting a small ship. When it moves, waves crash and the air hums with tension, signaling its presence long before it is fully visible.

Drowned-Turso

Large monstrosity (sea spawn), chaotic evil

---

Lore & Role

The Drowned-Turso is the first stage of Iku-Turso’s spawn, a cursed servant born from the ocean’s depths. It drifts near shipwrecks and coastal waters, dragging sailors and unwary travelers into watery graves. Though weaker than its older siblings, it is relentless and cunning, attacking in packs to scout and harass enemies on behalf of Storm-Turso and Doom-Turso.

• Summon Allies. One Drowned-Turso ally appears if fewer than three are present.

---

Tactics

Drowned-Turso attacks in coordinated packs, using Tentacle grapples to isolate prey while weaker adventurers are dragged underwater. It favors melee combat, pulling key targets into hazards like whirlpools or wreckage, and retreats into deeper water if badly injured.

---

Physical Description

The Drowned-Turso is roughly 25–30 feet long, with a muscular, sinuous body coated in algae and barnacles. Tentacles sprout from its sides, tipped with sharp spines, and its jaws contain serrated teeth capable of tearing wood and flesh alike. Pale, glowing blue eyes reflect predatory intelligence, and its movements churn the water, signaling danger long before it surfaces.
