Through your constant practice with your whip it becomes more useful in and outside of combat.

In combat

• Grants you the ability to attempt a disarming strike as your action; You may attack any target within your whips range and attempt to make them drop an item of your choice they are holding. The target must make a STR save with a DC equal to 5 + the damage your whip attack deals (5 + dex bonus + proficiency bonus+ 1d4) (Can only be used once per turn) (If you are a fighter with Disarming attack already you cannot use both in the same turn)
• As an action you may attempt to grapple a loose item within the reach of your whip and pull it toward you.  You must make a Dex (Acrobatics) check and pass with a DC 15 (Medium Difficulty).  The maximum weight that you can pull toward you is 10 times your Strength bonus.
• If you are a fighter with Trip attack - You may now attempt to trip any creature Huge or below and get advantage on your Superiority dice roll to trip small targets.
