You have mastered several techniques with the whip and are extremely skilled in combat with it. While using a whip you gain the following benefits: 

• your whip damage die now increases to a d6 instead of a d4
• As an action, you are able to latch onto small items within reach and pull them towards you, anything under 2 pounds not being worn or carried can be pulled into your hand, thrown as an improvised weapon at a target, or given to a willing creature within reach.
• As a reaction when something leaves your weapon reach, you can attempt to trip the target. Make a Strength (Athletics) check contested against the target's Strength (Athletics) or Dexterity (Acrobatics), on a success the target is knocked prone.
• You gain advantage on prone enemies at any range within reach.
• As an action, you are able to swing from overhanging poles, branches or similar sturdy things using your whip and hanging from it. Performing this acrobatic move requires no check if there is suitable ground to land on.
