Fathomless
You have plunged into a pact with the deeps. An entity of the ocean now allows you to draw on its thalassic power. Is it merely using you to learn about terrestrial realms, or does it want you to open cosmic floodgates and drown the world? Whatever the reason for your pact, the sea and its unknown depths call to you.

Subclass Features
Patron Spells
Your newly revealed Patron ensures you always have certain spells prepared. You know the following spells and they do not count towards the number of spells you can prepare.
Tentacle of the Deep
You can magically summon a spectral tentacle that strikes at your foes. As a bonus action, you create a 10-foot-long tentacle at a point you can see within 60 ft 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 ft of it. On a hit, the target takes 1D8 Cold damage, and its speed is reduced by 10 ft until the start of your next turn.
As a bonus action on your turn, you can move the tentacle up to 30 ft and repeat the attack.
You can summon the tentacle a number of times equal to your Proficiency Bonus per long rest.
Gift of the Sea
You gain a Swimming speed of 40 ft, and you can breathe underwater.
Guardian Coil
Your Tentacle of the Deeps can defend you and others, interposing itself between them and harm. When you or a creature you can see takes damage while within 10 ft of the tentacle, you can use your reaction to choose one of those creatures and reduce the damage to that creature by 2D8.
The damage dealt by your tentacle is increased to 2D8.
Oceanic Soul
You are now even more at home in the depths. You gain Resistance to Cold and Force damage.
Grasping Tentacles
You summon additional tentacles to aid your patron. You learn the spell Evard's Black Tentacles. It counts as a Warlock spell for you, but it doesn't count against the number of spells you know. You can also cast it once without using 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 magic bolsters you, granting you a number of temporary hit points equal to your Warlock level. Moreover, damage can't break your concentration on this spell.
All Consuming Whirlpool
You can create a funnel that leads straight into the maw of your patron. As an action you summon an ethereal whirlpool of inky water in a 60 ft diameter that is 90 ft tall centered on you that remains for one minute. The area within the whirlpool is Difficult Terrain and each creature other than you and those you designate must make a STR saving throw DC equal to your spell save DC at the start of each of their turns and on a failed save is pulled 20 ft toward the center. If a creature is pulled to the center it vanishes for a brief period taking 4D6 Psychic damage as their mind is ravaged and is teleported to a random space outside of the whirlpool.
If you create a second whirlpool the first whirlpool vanishes.
Fathomless Plunge
You can magically open temporary conduits to watery destinations. As an action, you can teleport yourself and up to five other willing creatures that you can see within 30 ft of you. Amid a whirl of tentacles, you all vanish and then reappear up to 1 mile away in a body of water you've seen (Pond size or larger) or within 30 ft of it, each of you appearing in an unoccupied space within 30 ft of the others.
Once you use this feature, you can't use it again until you finish a short or long rest.
