You master the whip, gaining the following benefits:

• You gain proficiency in the whip and can treat it as

if it had the light property.

• When you hit with a weapon attack using a whip

and have advantage on the roll, the whip deals an

additional 1d4 slashing damage.

• When you hit a Medium or smaller creature with an

opportunity attack made with a whip, the target

must succeed on a Strength saving throw or be

knocked prone (DC 8 + your Strength or Dexterity

modifier + your proficiency bonus).

• When you take the Disarm action (as described in

Chapter 9 of the Dungeon Master's Guide) using a

whip, you have advantage on the attack roll.
