Herein lies a half-race for every official 5e race in the PHB, EE companion, SCAG, and Volo's. Most features of these races are given only by name. You will have to look them up in official source material to learn the details.

Scoring:
These races are scored roughly according to the Musicus scale with insight from the Detect Balance scale. My goal was to balance them against a 6.5-point average. The average official race is closer to 6, but the lower-strength races get somewhat less play because of this, and so creating new races would most likely gain interest and not be overpowered at around 6.5 Musicus points, which is approximately 26 Detect Balance points. Each half-race is 3 points, or 3.5 points if they have Darkvision or other features that are hard to split/decrease in value.

Yuan-Ti:
I have presented a full Yuan-Ti replacement that is balanced at 7.5; the original would score an 11.5, which is way beyond reasonable.

Turtlefolk:
Also included is my new Turtlefolk race, a Half-Turtle race, and a racial feat. I would love feedback on these in particular.

Rules for Ability Score Improvements (ASIs):
No character may gain more than a +2 ASI to any ability score from racial benefits. If a character chooses an option that would result in a +3, his bonus is nonetheless limited to +2. There should be no circumstance under the following guidelines to create such a problem: any time such an issue could occur, a player always has an alternate choice that he could choose instead.

Balancing Existing Races:
Several of the standard player races are noticeably weaker than others. In order to bring some the weaker ones closer to the 6.5 target, I’ve made a few adjustments:

Dragonborn:
- Your breath weapon uses your Str or Con modifier, your choice.
- Powerful Breath. Your breath weapon ignores damage resistance.
- Menacing. You gain proficiency in the Intimidation skill.
Gnome:
- Forest Gnome. You gain proficiency in the Nature or Animal Handling skill.
- Rock Gnome. You gain proficiency in the History skill.
- Deep Gnome. You gain proficiency in the Arcana skill.
Half-Orc: You gain proficiency in the Athletics skill.
Halfling: Your subrace ASI is +2 rather than +1.
Human: 2 skill or tool proficiencies and a 30 ft. climbing or swimming speed
Tiefling: You gain proficiency in the Deception skill.
Genasi:
- Elemental Expertise. When you make an Intelligence ability check related to your elemental affinity, you can add twice your proficiency bonus, instead of any proficiency bonus you normally apply.
- Air Genasi: You gain resistance to lightning damage.
- Earth Genasi. You gain resistance to poison damage.
Goliath: You gain proficiency in the Intimidation skill.
Kobold: Stealth proficiency, Superior Darkvision (120 ft.)
Orc: Athletics proficiency, Superior Darkvision (120 ft.)

Half-Human:
The Half-Human half-race looks suspiciously like the Variant Human that is viewed as so overpowered. Here I have removed the skill proficiency and limited the feat options to a list of those generally weakly regarded. Are there feats in this list that you would remove, or others that you would add?

Selecting Half-races:
Choose one subrace for each half-race. Your Size and base walking speed match those of the smaller race, but your character height and weight are yours to choose as you please befitting such a race combination. If you gain Darkvision from multiple sources, you gain the best version, but the benefits do not stack.

Darkvision Variant:
https://www.reddit.com/r/DnDBehindT..._i_hate_it_its_no_fun_and_it_can_die/cv13uj6/
I read this alternate take on Darkvision by transmogrify on Reddit. I think it would make the game more interesting to require more light management and less, “Everybody has darkvision except the human, so we’ll just ignore darkness this campaign.”
Darkvision. You have superior vision in dim conditions. You can see in dim light within 60 feet of you as if it were bright light.
Superior Darkvision. Within the range of your darkvision, you can see in darkness as if the darkness were dim light. You can’t discern color in darkness, only shades of gray. If a source of bright light is within the range of your darkvision, you cannot use this ability.
