You have the keen wherewithal to use flexible weapons to their fullest.

• You can ignore the Reach property of finesse weapons when making an attack of opportunity.
• You can interact with and pick up items within the reach of your whip (such as shutting a door, grabbing a chandelier to swing on, or picking up a sword).
• As a bonus action while you're wielding a whip, you can attempt to grapple or shove a creature within the whip's reach. When you do so, you can make a Dexterity (Sleight of Hand) check in place of a Strength (Athletics) check to initiate or maintain the grapple. You can't grapple more than one creature per whip, and while grappling a creature this way you can't attack using that whip.
