Your Charisma increases by 2, and your Dexterity or Strength increases by 1.

You can speak, read, and write Common, and one extra language of your choice.  The Vampiric often need to adapt their language and manner of speaking depending on the society they are blending in with, or to charm the locals into looking the other way when they perform dubious actions.

Vampiric age at a rate 2x slower than their race of origin.

Vampiric come from a variety of backgrounds and beliefs, though most tend to be Lawful in nature.

A Vampiric's size is based on the non-Vampiric aspect of its race, and can therefore range from a small to large humanoid.

With your enhanced reflexes, your base walking speed is 40 ft.

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.

Your darkvision has a radius of 60 feet.

As a Vampiric, you can use your retractable fangs as a powerful melee attack during battle.  As an action on your turn, make a melee attack against a target within range, adding your proficiency and STR or DEX modifier (whichever is higher).  On a hit, the target takes piercing damage equal to 2d6 + STR bonus modifier.  If the target is grappled or incapacitated, the attack is an automatic critical hit.  

When you use this feature, if the target is a living creature, you may choose to drink the target's blood.  Doing this regains hit points equal to half of the damage taken (rounded up), and satisfies any craving for blood you may have.  If you choose to use this feature, you cannot use reactions until the end of your next turn.

Vampires have a unique talent for making convincing arguments, some would say magically so.  Once per day as an action, you may use the Charm Person spell at 1st level without using a spell slot.  CHA is the spell-casting modifier for this spell.

As a Vampiric, it is important to drink the blood of a living creature at least once every week, and at least a pint at a time.  Neglecting to do so will result in a reduction of 10HP to your hit point maximum for every 7 days gone without blood, to a minimum of 1HP.  In addition, every 30 days fasting will result in 1 point of exhaustion.  Upon drinking, your hit point maximum immediately returns to normal, and one point of exhaustion may be removed every subsequent long rest.

In addition, the longer you maintain a blood fast, the harder it becomes to resist temptation.  Natural instinct will gradually compel you to attack living creatures around you until you are satisfied, or until you perish.

You can use your action to Wildshape into a Bat for 1 hour.  While in this form, you can't speak or cast spells, your walking speed is 5 feet, and you have a flying speed of 30 feet.  Your statistics match that of a Bat, apart from your alignment, personality, Intelligence, Wisdom, and Charisma scores, which remain the same.  Anything equipped to you transforms with you, but anything that is held drops to the floor.  You revert to your true form early if your hit points reach zero, or if you choose to revert as a bonus action.  You regain the ability to use this feature after a long rest.
