Mockingblade

This magic sword helps you more effectively add insult to injury. The sword has 6 charges and regains 1d4 + 2 expended charges daily at dawn. When you hit a creature with this weapon, you can immediately use a bonus action to expend 1 of its charges to cast the vicious mockery spell from it, using your spell save DC, against that creature. When you do, any words you use to insult the creature appear written along the blade for 1 minute or until replaced by a new insult.

When a creature rolls a 20 on a saving throw against a vicious mockery spell cast from the blade in this way, the face adorning the sword’s hilt screams insults at you instead until the end of your turn. The insults are audible out to 30 feet and are directed at your deepest insecurities and regrets. Any creature that hears these insults is made aware of your weaknesses, granting it advantage on its next attack roll against you until the start of your next turn. Once the sword screams at you in this way, it can’t be used to cast the vicious mockery spell again until 1d4 days have passed.
