Deep One Bloodline

You either have a Deep One ancestor or you are the result of some terrible experiment.

Call of the Sea

Swimming no longer costs you extra movement but if you already have a swimming speed it increases by 10 feet. In addition, you can speak, read, and write Deep Speech. Whenever you make a Charisma check wheninteracting with deep ones, your proficiency bonus is doubled if it applies to the check.

 

Deep One Physique

At 1st level, your eyes enlarge. You have darkvision 60 ft. If you already had darkvision, the range increases by 30 feet. Your skin is also covered in a layer of fish-like scales. When you aren’t wearing armor, your AC equals 13 + your Dexterity modifier.

Home in the Depths

Starting at sixth level you are at home in the deep and gain the following benefits. You can breath air and water, you gain resistance to cold damage and can't be harmed by water pressure. You also have advantage on stealth checks made while underwater.

Unlocked Magic

At 14th level you learnt enough about the workings of magic, you can improvise the use of items even when they are not intended for you, you ignore all class race level requirements on the use of magic items. If you could already use an item with such restrictions, you can spend 1 sorcery point as part of activation of activating a magic item to use your own spell attack modifier and your own spell save DC for that activation if they are better than the items.

Dreams of the Sea

Starting at 18th level immediately when you finish a long rest you can cast dream without expending a spell slot the dream you create must involve the sea, but you can observe the targets response to it. If you are in or near a body of water you can cast suggestion on the target regardless of range and without expending a spell slot once during the dream compelling it to come to that body of water as soon as it awakens.

Life from the Sea

Starting at 18th level the sea gives you vitality. If you finish a long rest that was spent entirely in sea water, you regrow any lost body parts and end any one effect reducing one of your ability scores. If you are killed and the majority of your remains is immersed in a body of sea water for 24 hours you return to life as if the spell raise dead had been cast upon them.
