The Leviathan

The ocean is vast, eternal, and merciless. Beneath its waves lie beings of unimaginable size and age, creatures older than empires, perhaps even older than the gods themselves. One such entity has taken notice of you—the Leviathan, a primordial terror that slumbers in the deepest trenches and coils through drowned ruins. Whether it is an ancient kraken, a serpent the size of continents, or the living will of the sea itself, this being has answered your call for power.

Warlocks of the Leviathan are bound to the ocean’s most alien truths. They channel abyssal pressure, summon unseen currents, and drown their foes in silence and darkness. Unlike sailors or druids who revere the sea as a giver of life, Leviathan warlocks embrace the ocean as a force of hunger, inevitability, and crushing inevitability. Their magic drips with salt and shadow, their whispers echo like waves in caverns, and their eyes often carry the abyssal glow of bioluminescence.

The Leviathan does not guide with words, but with tides. To its servants, patience and inevitability are virtues, and the drowning of kingdoms is as natural as the turning of the moon. Those who bear its pact are heralds of its will—dreaded on land and sea alike, marked by the deep’s relentless pull.

Level 3: Abyssal Grasp (3rd Level)

3rd-level Leviathan feature

The Leviathan’s power flows through you like crushing tides, tugging at the world around it. When you hit a creature with Eldritch Blast, you can pull it up to 10 feet toward you, as though unseen tentacles or currents drag it into your reach.

In addition, you learn the spell Grasp of the Void (reflavored as a watery or abyssal effect if desired) if you do not already know it, and it does not count against your number of spells known. When cast, the spell manifests as writhing tentacles or relentless undercurrents that grapple and crush your foes, dealing both force and psychic damage while they struggle against the deep’s pull.

The Leviathan’s grasp is inexorable, a reminder that the depths claim what they desire—and now, through you, they can reach the surface.

Level 6: Pressure of the Deep (6th Level)

6th-level Leviathan feature

The abyss does not merely exist—it presses down, relentless and unyielding. You have learned to channel this crushing force through your very presence. You gain resistance to cold damage, and you are unaffected by the hazards of deep-water pressure.

When you deal damage with a warlock spell, the Leviathan’s weight bears down on your target. You can force a creature you hit with a spell to make a Strength saving throw against your spell save DC 8. On a failed save, invisible currents or abyssal pressure restrain the creature until the start of your next turn. On a successful save, the creature resists but remains aware of the oppressive force surrounding it.

Enemies feel the deep’s inexorable pull whenever you strike, as if the ocean itself seeks to drag them into the void.

Level 10: Drowning Aura (10th Level)

10th-level Leviathan feature

You become an avatar of the deep’s suffocating embrace. You can breathe underwater and gain a swim speed of 40ft.

The crushing currents of the abyss radiate from you in a 10-foot aura. At the start of each hostile creature’s turn within the aura, it must make a Constitution saving throw against your spell save DC 8. On a failed save, the creature begins choking as water fills its lungs, becoming incapacitated until the end of its turn. Creatures that do not need to breathe are unaffected.

The Leviathan’s presence is unmistakable: enemies feel the ocean’s pressure pressing on them, a reminder that the depths claim what they desire.

Level 14: Avatar of the Leviathan (14th Level)

14th-level Leviathan feature

You call upon the full, terrifying power of the Leviathan, manifesting its presence in the material world. For 1 minute, a 30-foot radius around you is filled with tentacles, crushing currents, and abyssal pressure. At the start of each of your turns while the aura lasts, choose one effect:

• Crushing Depths: Hostile creatures in the aura must make a Strength saving throw against your spell save DC or take 4d8 bludgeoning damage and be knocked prone.

• Drowning Dark: The area fills with black, abyssal water. Hostile creatures in the aura are Blinded, and the terrain counts as difficult terrain. You can see normally.

• Undertow: Once per turn when you hit a creature with an attack or spell, you can pull it up to 20 feet in any direction within the aura.

The manifestation of the Leviathan is awe-inspiring and terrifying; the ocean itself seems to rise at your command, dragging your enemies toward their doom. You can use this feature once per long rest.
