Pact of the Fathomless

You have made a pact with a powerful entity that lurks in the lightless depths of the ocean. Such patrons include krakens, aboleths, ocean gods, and other sea creatures of ancient and alien power. Your patron's influence reaches up through fathoms of dark water to touch your mind, granting you command over the cold and the crushing deep.

Tentacle of the Deeps

1st-level Pact of the Fathomless feature

At 1st level, you can magically summon a spectral tentacle that strikes your foes. As a bonus action, you create a 10-foot-long tentacle at a point you can see within 60 feet of you. The tentacle lasts for 1 minute or until you use this feature to create another tentacle.

When you create the tentacle, you can make a melee spell attack against one creature within 10 feet of it. On a hit, the target takes \(1d8\) cold damage, and its speed is reduced by 10 feet until the start of your next turn.

As a bonus action on your turn, you can move the tentacle up to 30 feet and repeat the attack.

You can summon the tentacle a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Gift of the Sea

1st-level Pact of the Fathomless feature

Also at 1st level, you gain a swimming speed of 40 feet, and you can breathe underwater.

Oceanic Soul

6th-level Pact of the Fathomless feature

At 6th level, you are now at home in the deep waters. You gain resistance to cold damage. Additionally, you can communicate with any creature that has a swimming speed, as long as you share a language.

Guardian Coil

10th-level Pact of the Fathomless feature

At 10th level, your Tentacle of the Deeps can defend you and others. When you or a creature you can see within 10 feet of your spectral tentacle takes damage, you can use your reaction to choose one of those creatures and reduce the damage it takes by \(1d8\).

Grasping Tentacles

14th-level Pact of the Fathomless feature

Starting at 14th level, you learn the spell Evard's black tentacles. It counts as a warlock spell for you, but it doesn't count against your number of spells known. You can cast it once without expending a spell slot, and you regain the ability to do so when you finish a long rest. Whenever you cast this spell, your patron's power reaches through the veil — you gain temporary hit points equal to your warlock level.
