Your mix of elven and changeling heritage grant you great charisma, as both your ancestrys are known for their looks. Elves, from their long life and their passing of knowledge, have taught you higher than average intelligence. The Changelings, known for their discretion and deception, have dexterity to lurk in their own shadows.

Your Charisma score increases by 2, your Dexterity score increases by 1 and your Intelligence score increases by 1.

Changelings mature slightly faster than humans -while they can transform to conceal their age- but with your Elven heritage, you live much longer than humans, however, often exceeding 200 years.

In their natural forms, they average between 5 and 6 feet in height, with a slender build. Your size is Medium.

Your base walking speed is 30 feet.

Your swimming speed is 30 feet.

Half-elves share the chaotic bent of their elven heritage. They both value personal freedom and creative expression, demonstrating neither love of leaders nor desire for followers. They chafe at rules, resent others' demands, and sometimes prove unreliable, or at least unpredictable. They are good and evil in equal numbers, a trait they share with their human parents. Changelings hate to be bound in any way, and those who follow the path of the Traveler believe that chaos and change are important aspects of life. Most tend toward pragmatic neutrality as opposed to being concerned with lofty ideals. Few changelings embrace evil.

You can speak Common, Elven, and two languages of your choice.

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

Thanks to your elven heritage, you have superior vision in dark and dim conditions. 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 can't discern color in darkness, only shades of gray.

As an action, you can transform your appearance or revert to your natural form. You can’t duplicate an appearance you’ve never seen, and you revert to your natural form if you die.

• You decide what you look like, including your height, weight, facial features, the sound of your voice, coloration, hair length, sex, and any other distinguishing characteristics. You also can’t appear as a creature of a different race or other size than you, and your basic shape stays the same. Your clothing and other equipment don’t change in appearance, size, or shape to match your new form, requiring you to keep a few extra outfits on hand to make the most compelling disguise possible.
• Even to the most astute observers, your ruse is usually indiscernible. If you rouse suspicion, or if a wary creature suspects something is amiss, you have advantage on any Charisma (Deception) check you make to avoid detection.

When a creature you can see makes an attack roll against you, you can use your reaction to impose disadvantage on the roll. You must use this feature before knowing whether the attack hits or misses. Using this trait reveals your shapeshifting nature to any creature within 30 feet that can see you. Once you use this trait, you can’t use it again until you finish a short or long rest.
