For 1 round your movement speed becomes 45ft and lightning fast. You get automatic advantage and sneak attack applied on any attack if made from behind a creature. None of your movement provokes opportunity attacks.

Each of your rapiers get an additional +3 to attack with a 1d6+3 to dmg. You may slash any creature on your way to your chosen final target/targets along a 20 foot path for a straight 6 piercing dmg. Your final target can be a single or an additional adjacent creature of MEDIUM or LARGE size with the other sword. Anything HUGE OR GARGANTUAN must have both swords target it alone.

You can choose to leave the vibrating magical copy in the creature you attacked (dealing 6 piercing dmg per round for 1 minute).

You can also choose to have the sword return to its twin at anytime for an additional 1d8 dmg to its original target and ( Deal 6 dmg to any creature in its returning path) Each creature in its path not resistant to piercing, must make a constitution save of 14 or take 1d4 bleeding for each turn until the end of your next turn. The copy disappears at the start of that next turn.
