Homebrew Descendant of Medusa Species Details

Descendant Names:

Descendant Traits:
Ability Score Increase-
Your Dexterity Score increases by +2, and your choice of Wisdom or Charisma increase by +1. 
Age-
Medusae, rare as they are, are rumored to have soled their souls to a fiend or deity in return for everlasting beauty, and can only mate with one another. This means that medusae may live for several centuries, with lifespans similar to that of a gnome or elf. As a result of the curse placed upon them in return for such longevity, their children's lifetimes are determined by the dealmaker of their ancestors' curse.
In short, the Descendant of Medusa will come of age at the same rate of other humanoids (around 20-30 years), but they can live up to 500-750 years. Whether a Descendant dies naturally or in battle, they will retain all of their youthful beauty until the point of death, upon which all of their visible age will return at once, their curse having been broken.    
Alignment-
Descendant alignment is exceptionally fluid, however being raised by cursed parentage who rely on lawful systems to keep their power, many fall easily into Lawful and Evil or Neutral traits. They may use their abilities to use and abuse legal systems to keep their political power in play, or to keep their claim on specific land as a way to protect their rare bloodline.  
Size-
Descendants will often fall along Elven height standards, with average statures of 5 - 6 1/2 ft. tall. This may vary some depending on size and flexibility of individuals serpent hair. Your size is medium. 
Speed- 
Your base walking speed is 30. 
Dark Vision-
With your serpentine eyes 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. (Player may customize this in their sheet if it is not automatically included.) You can’t discern color in darkness, only shades of gray. You cannot see through the eyes of your snake(s) that live upon your head, though they can warn you of danger that they see, if you choose to heed them. You and Your serpentine hair have a Passive Perception determined by your Passive Wisdom found in Senses. 
Blending In-
While Descendants tend to be more humanoid in shape and facial features than their cursed parentage, they still have gray-spattered skin, with base skin colors being as varied as humans, including additional tones of green, gray, and yellow. This skin variation in addition to their serpentine eyes and hair make Descendants more noticeable in a crowd, but may allow them to be played more stealthily in more natural of forested settings. 
Petrifying Gaze- 
Your look can turn other creatures to stone. As an action, you can target one creature that can see you within 30 feet of you with your gaze. At the start of that creature’s next turn, as long as you aren’t incapacitated and it can still see you, it must make a Constitution saving throw with a DC equal to 8 + your proficiency bonus + your Constitution modifier. On a failed saving throw, the creature begins to turn to stone and is restrained. The restrained creature must repeat the saving throw at the end of its next turn, becoming petrified on a failure or ending the effect on success. The petrification lasts for 1 minute, or until the creature is freed by the greater restoration spell or other magic. When you reach the 17th level, the petrification is permanent unless removed by magic, and if a creature fails its initial saving throw by 5 or more the creature instantly turns to stone.
Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can’t see you until the start of its next turn, when it can avert its eyes again. If the creature looks at you in the meantime, it must immediately make the save.
Once you use this feature you can’t use it again until you finish a long rest.
Snake Hair- 
Your scalp is teeming with living snakes (number may very from 1-100. They may also vary in type). Your Snake(s) are a part of you and can be commanded, however they do also have minds/personalities of their own. If a snake is note being used in combat they will default to the Dodge action during attacks and reactions. You can use your hair to make melee weapon attacks with. If you hit with it, you deal piercing damage equal to 1d4 + your Dexterity modifier. These serpents are not poisonous. 
Languages- 
You can speak, read, and write Common and Infernal.
