A creature with truesight can, out to a specific range, see in normal and magical darkness, see invisible creatures and objects, automatically detect visual illusions and succeed on saving throws against them, and perceives the original form of a shapechanger or a creature that is transformed by magic. Furthermore, the creature can see into the Ethereal Plane.

You have a flying speed of 30 feet, which doesn't function above 10 feet.

You are proficient with the Bite Attack (melee). This does 1d6 + Strength Modifier piercing damage. When using Bite as an Attack Action, you can use your Bonus Action to Drain a living victim (this does not require another attack roll, as you have 'latched on' to your victim) causing an additional 1d6 necrotic damage which you then gain as healing. After performing a Drain Attack, you must roll a Wisdom Saving Throw DC 20 - Wisdom Modifier. On a success, nothing happens; on a fail, you are unable to willingly release your victim and begin to grapple them. If you are not physically or otherwise forced to release your victim before your next round, you must perform the same Drain action and repeat your saving throw, locked at the victim's throat until you make your save, are physically removed, the victim breaks free or dies. If you take damage whilst Draining a victim, you may roll another Wisdom Saving Throw.

You have the ability to make a bite attack against either a willing creature, a creature that is charmed or grappled by you, or a creature that is incapacitated or restrained. You can use your Strength or Dexterity for your bite's attack roll. On a hit, your bite deals necrotic damage equal to 1d8 plus the ability modifier used to make the attack roll. You may also choose to gain temporary hit points equal to the amount of necrotic damage dealt with this attack.

Whenever you successfully strike a creature with blood using your fangs, you may choose to enter a Blood Frenzy. Until the end of your turn, you may use a bonus action to make a fang attack against a target.
