Blade Dancer

When wielding your weapon of choice you are so fluid and graceful that combat becomes more like a dance than actual fighting for you.

Choose one bladed melee weapon type with which you are proficient. When wielding this weapon you gain the following benefits:

• If the weapon does not have the finesse property, it gains the finesse property while you wield it.
• You gain advantage on Performance checks in involving the weapon.
• When a creature misses you with an attack roll while you are wielding your weapon of choice, you can use your reaction to force it to make a Wisdom saving throw (DC 8 + your proficiency bonus + your Charisma bonus), becoming Charmed by you until the end of its next turn on a failure. The Charmed condition ends if you deal damage to the creature. You can do this a number of times per long rest equal to your Proficiency bonus.
