You have practiced extensively with a whip, turning it into a dangerous weapon in your hands:

• Increase whip damage die from 1d4 to 1d6.
• While you are wielding a whip, other creatures provoke an opportunity attack from you when they enter your reach.
• Before you make an attack with a whip, you can choose to take a -5 penalty to the attack roll.
  • If the attack hits, you can either:
    
    • add +5 to the attack's damage.
    • Choose to attempt a disarm of 1 object held by the target. Make a Strength or Dexterity check vs target's Strength saving throw.
    • Choose to attempt a grapple instead of damage. Make a Strength check vs target's Strength of Dexterity saving throw.
