Aurum & Argentum

This gold and silver set of daggers seem ordinary when used on their own, but are magically amplified when used in tandem.

Twin Blades. When you hold one of the daggers in each hand, they are considered magical and grant you a +2 bonus to attack and damage rolls made with them.

Perfect Rhythm. When you engage in Two-Weapon Fighting using both daggers, you can add your ability modifier to the damage of the second attack. If the first dagger attack hits a creature during the Attack action, the second dagger attack made that turn is rolled with advantage.

Crosscut. If a creature is hit by both daggers in the same turn, the second hit deals an additional 2d4 piercing damage, and the creature cannot make opportunity attacks against you until the start of your next turn.

Flash of Gold and Silver. Once per turn, after you hit a creature with both daggers, you can immediately move up to 15ft. without provoking opportunity attacks.

Dance of Twin Serpents (1/Short Rest). When you take the Attack action, you can make one additional dagger attack with Aurum or Argentum.

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