Disarming Look. The blade enhances your force of personality and grants a visible thorny magical aura to the border of your eyes that starts spreading to the sclera when this weapon’s features are used. 

When a creature you can see targets you with an attack, you can use your reaction to gain a bonus to your AC equal to your charisma modifier against the triggering attack.
You can use this feature an amount of times per long rest equal to your proficiency bonus 

Thorny Charm. Twice per long rest when you hit a creature with a melee attack made with this weapon, you can use your reaction to cast Charm Person or Suggestion on the target using the weapon, without requiring any components.
If a creature is charmed by you and the charmed condition would end if you did anything harmful to the creature or if the creature is asleep, you can make one attack with this weapon against that creature without ending the condition. You can benefit from this effect against a single creature once per 24 hours. 

If a creature is suffering from an effect that allows them to repeat the saving throw against that effect each time they take damage or something hostile is done against them. You can force these saving throws to be made with disadvantage when imposed by your attacks with this weapon.
