You can have your Dexterity Score or your Charisma Score increases by 2, and your Intelligence Score or your Charisma Score increase by 1. You can only choose one of each selected option.

Although Elves reach physical maturity at about the same age as humans, the Elven understanding of adulthood goes beyond physical growth to encompass worldly experience. An Elf typically claims adulthood and an adult name around the age of 100 and can live to be 750 years old.

Alike Elves, Yuan-Ti range from under 5 to over 6 feet tall and have slender builds. Your size is Medium.

Your base walking speed is 35ft.

Because of your time spent in dark and dim places, such as: forests, caves, twilit forests, etc; you have a superior Darkvision of 60ft.

You have advantage on saving throws against being charmed, and magic can't put you to sleep.

You are immune to poison damage and the poisoned condition.

You have proficiency in the Perception Skill.

Alike Elves, Yuan-Ti Eladrin do not sleep. Instead they meditate deeply, remaining semi-conscious, for 4 hours a day. The Common word for this meditation is "trance." While meditating, you dream after a fashion; such dreams are actually mental exercises that have become reflexive after years of practice. After resting in this way, you gain the same benefit a human would from 8 hours of sleep.

A few years after the mysterious disappearance of your parents, you developed a magical ability known as Fey Step. After spending time practicing, you gain the following ability:

As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see. Once you use this trait, you can't do so again until you finish a short or long rest. When you reach 3rd level, your Fey Step gains an additional effect based on your season; if the effect requires a saving throw, the DC equals 8 + your proficiency bonus + your Charisma modifier. The effects are as follows:

• Autumn. Immediately after you use your Fey Step, up to two creatures of your choice that you can see within 10 feet of you must succeed on a Wisdom saving throw or be charmed by you for 1 minute, or until you or your companions deal any damage to it.
• Winter. When you use your Fey Step, one creature of your choice that you can see within 5 feet of you before you teleport must succeed on a Wisdom saving throw or be frightened of you until the end of your next turn.
• Spring. When you use your Fey Step, you can touch one willing creature within 5 feet of you. That creature then teleports instead of you, appearing in an unoccupied space of your choice that you can see within 30 feet of you.
• Summer. Immediately after you use your Fey Step, each creature of your choice that you can see within 5 feet of you takes fire damage equal to your Charisma modifier (minimum of 1 damage).

Because a relationship between a Yuan-Ti Pureblood and an Elardrin is greatly discouraged and frowned upon, Yuan-Ti Eladrin tend to be abandoned by the age of 10 or their parents killed, before the time comes, Yuan-Ti Eladrin learn to speak, read, and write in Common, Elvish, and Draconic.
