As a bonus action, you can draw upon your Drakonic heritage to transform into a hybrid form for 10 minutes. You can use this feature a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a long rest. You can end this transformation early as a bonus action.

When you undergo your Drakonic Shift, your body surges with power, becoming a bipedal fusion of humanoid and dragon. Your size remains Medium, but you grow taller and more muscular, and your skin is overtaken by jagged, elemental scales. While in this form, you gain the benefits of your Natural Armor, Draconic Senses, and Apex Weaponry traits.

Your scales are as hard as iron. While in your hybrid form, your Armor Class equals 13 + your Dexterity modifier. You can use a shield and still gain this benefit, but you cannot combine this calculation with other forms of unarmored defense or worn armor.

While in your hybrid form, your eyes slit like a predator’s and your senses sharpen to detect the slightest shift in the air. You gain Blindsight out to a range of 10 feet, allowing you to effectively see anything within that range even if you are blinded or in total darkness.

Your hands transform into lethal, hooked claws. These are natural weapons which you can use to make unarmed strikes. On a hit, they deal slashing damage equal to 1d6 + your Strength or Dexterity modifier (your choice) instead of the bludgeoning damage normal for an unarmed strike.

Your blood carries the essence of the ancient dragons. Choose one damage type from the following: Acid, Cold, Fire, or Lightning. You have resistance to that damage type, taking only half damage from it.

The primal curse that grants you power also leaves you susceptible to the "purity" of silver. You have vulnerability to damage from silvered weapons, meaning you take double the damage from attacks made with them.
