Oath of the Tides

A paladin raised on the sea may take this oath as a mark of respect for the way of life on the seas and in honour of the gods that rule over them.

Channel Divinity

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

Undrowning. You can use your Channel Divinity to attune you and your allies to the depths of the sea. As an action, you can grant up to ten willing creatures with the ability to breathe underwater. Creatures affected by this ability also retain their normal modes of respiration. The benefits granted by this ability last for 8 hours.

Siren's Call. You can use your Channel Divinity to speak in lulling tones, enchanting those nearby. As an action, any creatures you choose within 30 feet of you must make a wisdom saving throw. On a failed save, they become charmed by you for 1 minute. The charmed creature can repeat this saving throw at the end of each of its turns, ending the effect on itself on a success.

At Home With Water

Due to your affinity with water, you gain access to the cantrip shape water when you take this Oath. You also gain a swim speed equal to your walking speed.

Oath Spells

You gain oath spells at the paladin levels listed.

Calm The Waves

Beginning at 7th level, you can imbue those around you with the calm of a peaceful sea. You and friendly creatures around you have advantage on wisdom saving throws.

At 18th level, the range of this aura increases to 30 feet.

Spirits of the Depths

Starting at 15th level, you can use your reaction to channel the spirits of the depths into your attack, which deals 2d10 cold damage and forces the creature to make a constitution save against your spell DC. On a failed save the creature takes cold damage equal to your wisdom modifier, making another save at the beginning of each turn until a success. 

Manifest Leviathan

At 20th level, you can channel the force of the great Leviathan.

Using your action, you undergo a transformation. For 1 minute, you gain the following benefits:

• At the start of each of your turns, you regain hit points equal to your wisdom modifier.
• You channel the waves and their flow, ignoring difficult terrain and adding 10ft to your speed.
• Enemy creatures within 10 feet of you have to make a wisdom saving throw, on a failed save they become frightened.

Once you use this feature, you can’t use it again until you finish a long rest.
