Disarming Duelist

Whenever you make a melee weapon attack while wielding a finesse weapon with which you are proficient, be it as part of an attack, bonus action, or even a reaction, you may attempt to Disarm the target as well, forcing it to drop one item of your choice that it's holding. Your attack roll, if it hits your target, is then also contested by the target's Strength (Athletics) check or Dexterity (Acrobatics) check. If you win the contest, on top of dealing that melee attack's usual damage, it also causes the defender to drop the aforementioned item of choice.
