You transitioned into undeath, but your transition was imperfect. Though you are a humanoid, you are susceptible to effects that target undead. You can regain hit points from spells like cure wounds, but you can also be affected by game effects that specifically target undead, such as a cleric’s Turn Undead feature. Game effects that raise a creature from the dead
work on you as normal, but they return you to life as a darakhul. A true resurrection or wish spell can restore you to life as a fully living member of your original race.

Your heavy jaw is powerful enough to crush bones to powder. Your bite is a natural melee weapon, which you can use to make unarmed strikes. When you hit with it, your bite deals piercing damage equal to 1d4 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.

You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.

You don’t need to breathe, and you don’t sleep the way most creatures do. Instead, you enter a dormant state that resembles death, remaining semiconscious, for 6 hours a day. While dormant, you have disadvantage on Wisdom (Perception) checks. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

Your Strength score increases by 2, and your Constitution score increases by 1.

The inherent breath weapon of your draconic heritage is corrupted by the necrotic energy of your new darakhul form. Instead of forming a line or one, your breath weapon now oozes out of your ghoulish maw. As a bonus action, you breathe necrotic energy onto your fangs and make one bite attack. If the attack hits, it deals extra necrotic damage equal to your level. You can’t use this trait again until you finish a long rest.

You can speak, read, and write Common, Darakhul and Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants.

Young dragonborn grow quickly. They walk hours after hatching, attain the size and development of a 10-year-old human child by the age of 3, and reach adulthood by 15. They live to be around 80.

Dragonborn tend to extremes, making a conscious choice for one side or the other in the cosmic war between good and evil (represented by Bahamut and Tiamat, respectively). Most dragonborn are good, but those who side with Tiamat can be terrible villains.

Dragonborn are taller and heavier than humans, standing well over 6 feet tall and averaging almost 250 pounds. Your size is Medium.

Your base walking speed is 30 feet.

You have resistance to necrotic damage and poison damage, you have advantage on saving throws against being charmed or poisoned.
