The Sea Lord

You have made a pact with a ruler of the deep, a mighty sea-being who dwells in hidden river caves or the dark depths beneath the waves. Some such beings seek to influence, corrupt, or gain knowledge from the surface world; others view surface-dwellers, including yourself, as feeble and ignorant prey. Such beings include Davy Jones, Father Dagon, the Leviathan, la Llorana, and Triton, the son of the sea.

Expanded Spell List

The Sea Lord lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Sea Lord Expanded Spells

Armor of the Deep

Starting at 1st level, your body grows protective patches of scales, barnacles, or coral. When you take damage, except for psychic damage, you may use your reaction to reduce the amount taken by your Charisma modifier + your warlock level (minimum of 1).

Waterborne

Starting at 6th level, you gain a swim speed of 30 feet, and you can breathe underwater.

That Which Lurks

Starting at 10th level, you gain darkvision out to a range of 60 feet. Additionally, you have advantage on Dexterity (Stealth) checks made to hide in places of water or darkness.

Drown in the Depths

Starting at 14th level, when you hit a creature with an attack, you can use this feature to instantly transport the target through the ocean depths.

The creature disappears and hurtles through a subaquatic realm. At the end of your next turn, the target returns to the space it previously occupied, or the nearest unoccupied space. If the target does not have a swim speed or the ability to breathe water, it takes 10d10 cold or piercing damage (your choice) as it is exposed to lightless, icy water or frenzied sharks and tearing coral.

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