Oath of the Sea Leviathan

The Oath of the Sea Leviathan is one to the Lesser Deity known as Uk'otoa. Uk'otoa is a many-eyed sea serpent who was imprisoned under the Lucidian Ocean by the cultist followers of his maker, Zehir the Cloaked Serpent. Servants pledging their lives to Uk'otoa often find themselves doing so under desperate duress at sea. A shipwrecked sailor floating on a piece of  debri adrift at sea may find a second chance should he agree to the Great Sea Leviathan's bidding. The last moments of consciousness for a drowning soul may be inclined to accept the offer at a second chance on life should they be propositioned by the visage of Uk'otoa. Some deep-sea dwelling creatures may have ties to protect the imprisoned resting place of Uk'otoa, and spend their lives devoted to his service until he is strong enough to break his binds and consume the world and its' treasures once more.

Channel Divinity

When you take this oath at 3rd level, you gain the following two Channel Divinity options.

Brine Washed: As an Action you may whisper the name "Uk'otoa" while clutching your Holy Symbol. One creature that you can see within 60 ft must make a Wisdom saving throw.  On a failed saving throw the target's mind is flooded with thousands of whispers and surged with terrifying images of The Great Sea Leviathan. It takes 3d6 psychic damage and begins vomiting sea water rendering it incapacitated until the end of your next turn. On a successful save, the target takes half as much damage and is not incapacitated. A deafened creature automatically succeeds on the save.

Surge of the Sea Leviathan. Upon activating as a Concentration: 1 Minute Bonus Action, your currently equipped melee weapon begins dripping with briny, brackish, sea-water. The next time you hit with this weapon for the spell's duration, your weapon bursts forth with a sudden forceful torrent of rushing sea-water. The attack deals an extra 2d6 force damage to the target. Additionally, if the target is a creature, it must succeed on a Strength saving throw or be pushed 10 feet away from you and knocked prone. It takes additional bludgeoning damage if it was knocked into a solid object for a damage amount equal to your STR modifier.

Uk'otoa's Undertow

At 7th level, when an Oath of the Sea Leviathan paladin is not incapacitated, they emit an aura for 10 feet. All creatures of the paladin's choice within the aura cannot be grappled nor restrained and can ignore penalties on movement or attacks while underwater. A creature already subject to the grappled or restrained condition that enters into the aura can spend 5 feet of movement to automatically escape nonmagical restraints. The range of the aura increases to 30 feet at level 18

6th Sense of the Sea-Serpent

At 15th level, once per short rest you can call upon the eyes of Uk'otoa as they appear around your body as amber-eyed tattoos. These eyes give you Advantage on the following skill checks for 1 hour or until your next short rest: Charisma (Deception), Charisma(Intimidation), Wisdom (Perception).

Additionally you can see invisible creatures and through normal and magical darkness.

Amber-Eyed Abolitionist

Uk'otoa's influence over time has evolved one of your eyes into that like the amber eyes of Uk'otoa. This allows you to have constant true-sight.

You also gain the ability to cast Dominate Monster as an action once per long rest. As long as the target creature has an innate swim speed it has disadvantage on saving against the spell. If successful the duration lasts up to 8 hours or until the creature succeeds saving throw.

If your oath to free Uk'otoa from his benthic binds has been fulfilled, or perhaps the Great Sea Leviathan himself has been felled and consumed, the benefactor reaps the following as reward:

As an action you may cast Darkness once per short rest.

As an action you may cast Tsunami once per long rest.

While underwater you may use an action to cast Psychic Scream once per dawn. Target creatures outside the water get advantage on saving throws.
