You have mastered combat with the whip, using it to greater effect to lash and snare your opponents. You gain the following benefits:

When you use a whip, its damage die changes from d4 to d6, and you treat it as a light weapon.

When you take the Attack action and attack with only a whip, you can use a bonus action to grapple the target of your attack.

While you are wielding a whip, other creatures provoke an opportunity attack from you when they enter your reach.
