You have honed your skills with a whip to their peak, allowing you to have more benefits to using one than the average person:

• You gain proficiency with whips.
• While you are wielding a whip, other creatures provoke an opportunity attack from you when they enter your reach.
• When you succeed on an attack roll with a whip at its maximum range the enemy takes an additional 1D8 Thunder damage.
• On a succesful melee attack with a whip, you can use your bonus action to attempt to disarm or trip the enemy. The enemy must succeed a Strength saving throw against Disarm or drop their weapon. The enemy must succeed a Dexterity saving throw against Trip or be knocked prone. The enemy automatically fails on Critical hit.  Save DC13 + Dex or Str Modifier (Player's choice)
