Your base walking speed is 35 feet.

When you determine your ability scores, increase one of those scores by 2, and increase a different one by 1. These increases can’t raise a score above 20. You follow this rule regardless of the method you use to determine the scores, such as rolling or point buy. If you are replacing your race with a lineage, replace any Ability Score Increases you previously had with these.

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character. The Player’s Handbook offers a list of widespread languages to choose from. The DM is free to add or remove languages from that list for a particular campaign. If you are replacing your race with a lineage, you retain any languages you had and gain no new languages.

Every creature in D&D, including every player character, has a special tag in the rules that identifies the type of creature they are. Most player characters are of the Humanoid type. A race option presented here tells you what your character’s creature type is.

Your creature type is both Humanoid and Aberration.

If an effect works on at least one of a creature’s types, that effect can work on that creature. For example, if you are both a Humanoid and an Undead, cure wounds works on you, since the spell works on a Humanoid.

Your size is Medium or Small (choose when you gain this lineage).

You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light.

You have a climbing speed equal to your walking speed. In addition, at 3rd level, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.

Your maw bite is a natural weapon, which counts as a simple melee weapon with which you are proficient. You add your Constitution modifier to the attack and damage rolls when you attack with your bite. Your bite deals 1d4 piercing damage on a hit. While you are missing half or more of your hit points, you have advantage on attack rolls you make with this bite.

When you use your bite and hit a creature that isn’t a Construct or an Undead, you can empower yourself in one of the following ways of your choice:

• regain hit points equal to the damage dealt by the bite
• gain a bonus to the next ability check or attack roll you make; the bonus equals the damage dealt by the bite

You can empower yourself with your bite a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
