The dagger known as The Scorned Woman is a weapon that has been passed down from assassin to assassin for generations, responsible for the deaths of thousands of generals, princes, kings, and drunk and abusive men. Soaked in so much blood throughout the ages, yet always just out of the reach of those who sought it. It is a weapon that is impossible to find, one that can only be given. It can only be wielded by a woman, and should a man touch the dagger, they are paralyzed for 24 hours. 

This magic dagger is an ornate weapon with a handle made from the horn of an Ancient Black Dragon, inlaid with gold and a very powerful blood diamond, and a curved blade forged of adamantine and silver, the metal folded around the fang of an Ancient Green Dragon. This dagger is incredibly light and sharp, forged to have a wicked edge, allowing attacks made with it to ignore resistance to piercing damage. You also get advantage on all Charisma checks and saving throws. The dagger also allows you to automatically succeed on any failed Charisma check or saving throw twice per long rest.

This dagger is more than just a pretty weapon and an ornate boon. It is also an extremely deadly weapon. Attacks made with this weapon deal an additional 3d4 acid and 3d4 poison damage. This damage ignores resistance to acid and poison damage and all damage dealt to men with this weapon is doubled.

In the event of a critical hit or surprise attack, you can choose whether or not to inject the target as with a toxin known only as Her Final Tears. The target takes 1d4 poison damage and is paralyzed for 1 minute. Then roll 1d4+1. The toxin has no other effects on the target until a number of days pass equal to the number rolled. On the final day, the target experiences hallucinations of a blood dripping down walls and a woman in white robes appearing in the corner of their eye. Next, they begin to hear the faint sounds of girls laughing and women crying. This persists throughout the final day. The target also experiences headaches, drowsiness, fevers, seizures. On the night of the final day, the toxin finishes its work on the targets' brain, causing them to go into a state of permanent paralysis and to witness their worst nightmares. The target takes 2d12 Psychic damage every minutes until they finally die with their eyes running with a stream of bloody tears.

This can only be done once every month. 

Proficiency with a Dagger allows you to add your proficiency bonus to the attack roll for any attack you make with it.
