Homebrew:Deepborn

(OOC: This is an implementation of the deepborn race from The Crooked Moon)

Deepborn are a fish-like species native to Olmarsh, typically rising up from the abyssal depths of the province's black sea—home to terrors beyond imagining known as the Hungry Ones. Immersed in a near constant eldritch presence that emerges from the deep and descends from beyond the stars, these folk manage their state of paranoia by embracing and harnessing the uncanny and cosmic.

While they are primarily piscine in their anatomy, they can possess features found in a wide variety of sea creatures, including cephalopods and crustaceans. They typically live for around 150 years, but certain members of occult orders have been known to live for 600 years.

Variant: Humanoid creature types

Several of the species in The Crooked Moon are creature types other than Humanoid. These type differences reinforce the unusual nature of these species, but they also come with concerns that can make these species more powerful than others. Not being Humanoid makes a character immune to the charm person spell, for example. Conversely, it potentially makes them susceptible to other effects, such as the protection from evil and good spell. If the GM or players are uncomfortable with these deviations from standard species, changing the creature type to Humanoid solves the dilemma, while the species' other traits preserve their narrative.

Deepborn traits

As a deepborn, you have these special traits.

Ability Scores.

When you create a character using one of the species in The Crooked Moon, increase one of your starting ability scores by 2 and another by 1, or increase three scores by 1 each. These increases can't raise a score above 20.

Your character can speak, read, and write Common and one other language that you an your GM agree is appropriate for the character.

Your walking speed is 30 feet, and you have a swimming speed equal to your walking speed.

Amphibious.

You can breathe air and water.

Darkvision.

Eldritch Gibbering.

Thanks to your eldritch connection to the Hungering Ones, you speak Deep Speech. As an action, you can gibber in that language. Each creature of your choice within 30 feet of you must succeed on a Wisdom saving throw (DC 8 plus your proficiency bonus and Intelligence, Wisdom, or Charisma modifier; choose the ability when you select this species) or roll a d6 and consult the table below. The effect lasts until the start of your next turn. Once any target fails its save against this trait, you can't use it again until you finish a short or long rest.

Endless Hunger.

As a bonus action, you can embrace your connection to the Hungering Ones. Until the start of your next turn, you know the location of any creatures that aren't Constructs or Undead within 60 feet of yourself, and your attack rolls against those creatures can't have disadvantage. Once you use this trait, you can't use it again until you finish a short or long rest.
