• Ability Score Improvement. Your Constitution and Intelligence scores become 18 if they aren’t higher.
• Induce Stasis. You can put a creature into a state of deep slumber so you can feed on it at your leisure. You can use your action to touch an incapacitated humanoid or a humanoid under the effects of your Charm trait. That creature then falls asleep and is unconscious until a remove curse spell or similar magic is cast on it. While in this state, the creature doesn’t need to breathe, eat, or drink.
  When using your bite attack against an affected creature, you can choose to reduce the piercing damage to 1.
  At the end of every 7 days, an affected creature can make a DC 15 Wisdom saving throw, waking up on a success. The creature awakens feeling weakened, taking a −4 penalty to all attack rolls, saving throws, and ability checks. Every time the creature finishes a long rest, the penalty is reduced by 1 until it disappears.
  You can induce this type of stasis in a number of creatures equal to your Intelligence modifier.
• Powerful Fangs. Your bite attack uses d8s for its damage dice instead of d6s. This bonus applies to both the piercing and necrotic damage.
