Enthralling Presence

Your turning by a vampire has changed you, granting you the following benefits:

• Increase your Charisma score by 1, to a maximum of 20.
• You can target one non-undead humanoid you can see within 30 feet. If the target can see you, they must succeed on a Wisdom saving throw or be charmed by you. The saving throw DC equals 8 + your proficiency bonus + your Charisma modifier. The charmed target regards you as a trusted friend to be heeded and protected. Although the target isn’t under  your control, it takes your requests or actions in the most favorable way it can, and it is a willing target for your bite attack. On a successful save, the creature becomes immune to any vampire's enthralling presence for 24 hours.
  
  Each time you or your companions do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until you die, are on a different plane of existence than the target, or take a bonus action to end the effect.
  
  Once you use this ability, you can’t do so again until you finish a long rest.
