Bastard of Strahd

You were born a product of Strahd Von Zarovich. As his spawn you have gained some of his power, but lack the weakness of a True Vampire.

Mistform Teleport: You may choose to turn your corporeal form into a mist as part of your movement. While in this shape you do not provoke attacks of opportunity and have the ability to fly. When you finish your movement your corporeal form returns and you lose the benefits granted by the transformation. If you are in the air you will fall from the height at which you ended your movement.

Vampiric Regeneration: As a Bonus Action you can regenerate a number of hit points equal to your proficiency bonus + your level + your constitution modifier. Any additional hit points regenerated above your maximum HP become Temporary Hit Points. You regain use of this ability after a long rest. 

Natural Armor: Your skin is tough giving you a natural armor equal to 13 + Your proficiency Bonus.
