You have mastered the art of the whip and can perform maneuvers most others cannot. You gain the following benefits:

• You can make a grapple check against an opponent using your whip provided they are within the reach of your whip. 
  • A whip can only grapple a single creature at a time.
  • A creature grappled by your whip is restrained until the grapple ends.
• Reel In: You can use a bonus action to drag a creature grappled by your whip towards you. To do so, make an additional grapple check. If you succeed, the creature is dragged 5 ft. towards you.
• Trip: You can make a bonus action to use your whip to trip up a creature within your reach. To do so, make a grapple check. If you succeed, the creature is knocked prone.
• You may add your proficiency bonus to ability checks and attacks made to disarm enemies when using a whip as a part of the check or attack.
• While you are wielding a whip, other creatures provoke an opportunity attack from when they enter your reach.
