Blade Dancer

Blade Dancers have trained in arcane talents, which allow them to imbue their weapons with the weave, allowing them to control their weapons from afar like puppets. Blade dancers can range from valiant knights to shady assassins, using their talents to confuse and cut down their foes. 

Weave Weapon

Beginning when you choose this Archetype at 3rd level, you gain access to the weave and can imbue one of your weapons with magic. This weapon becomes your weave weapon, and you may only have one of these weapons at a time (you gain the ability to possess additional weave weapons at higher levels (5th, 11th and 20th)). You can make a weapon you own a weave weapon by spending 1 hour of time to imbue the weapon with magic, if you already have your maximum amount of weave weapons imbued, imbuing another disenchants the previous one.

Weave Weapon (Any dagger, scimitar, shortsword, longsword, or greatsword): Weave Weapons can be activated as a bonus action. Activating a Weave Weapon allows the weapon to float in air, fly around, and attack as per the wielder's will. The weapon uses your ability to make attacks and has a movement speed based on the weapon. (Daggers: 40 ft, Shortswords and Scimitars 30 ft, Longswords 20 ft, Greatswords 10 ft). Using a bonus action to activate the weapon allows you to also move the weapon to a target. Weave weapons can attack whenever you make an attack on your turn, however you can only move them or deactivate them as a bonus action. You can command any number of weave weapons to move using a single bonus action, however, each weapon attack requires a separate use of an attack (any number of attacks you have as the part of the attack action). To control a weave weapon you must have at least one free hand.

A weave weapon can move up to 60 ft away from the wielder before it loses it's connection to the weave and drops to the ground, it regains magic when it returns to the hand of the wielder to be re-activated. 

Dancing Parry

Starting at 7th level, if a Weave Weapon is activated an within 5 ft of you, if you are targeted by a ranged or melee attack, including spell attacks, you may add your proficiency bonus to your armor class for the attack, possibly allowing you to parry the blow. 

Strings of Fate

At 10th level, when you or an ally within 60 ft misses an attack with a Non-Weave Weapon you can choose to add your proficiency bonus (again if it is already added) to the attack, possibly causing the attack to miraculously hit. This feature can be used on melee and ranged weapon attacks. You can use this feature once per long rest. 

Weave Parry

Starting at 15th level, if you possess an activated Weave Weapon that is within 5 ft of a Spell being cast, you can attempt to cancel the spell. Make a spell casting ability check, the DC being 10 + the level of the spell cast. On a success, the spell is cancelled. You can use this feature a number of times equal to your intelligence modifier per long rest. 

Dance of Death

At 18th level, you gain high level control with your weave weapons. Once per long rest you can tug on the strings of the weave with all your strength, using an action you can instantly move all of you weave weapons to a single target within 60 ft of you and have them all make attacks against the target.
