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.

Humans vary widely in height and build, from barely 5 feet to well over 6 feet tall. Regardless of your position in that range, your size is Medium.

You have Resistance to Lightning damage and Thunder damage.

Spirit of the desert. As a bonus action you may transform into the form of a jackal or a hawk. While in this form, you can falteringly understand the languages you know, but have access to none of your other features. You may revert to your humanoid form as a bonus action. If you fall to 0 hit points while in this form, turn back to your humanoid form and carry over any extra damage.

As a bonus action, you can assume your accursed transformation. This transformation lasts for 1 hour, until you die, or until you revert to your normal form as a bonus action. Transforming in this way takes a heavy toll on your physical form, each time you transform you take damage equal to your Proficiency Bonus times your Proficiency Bonus. (e.g. at level 1, you will take 2*2 = 4 damage, but at level 17 you will take 6*6 = 36 damage.) This damage cannot be reduced in any way.

While this effect is active and you aren’t wearing armor or wielding a Shield, you gain the following benefits:

Dread Blindness. You have advantage to save or end the Frightened on yourself.

You can speak, read, and write Common and Celestial.
