You have mastered the ways of the whip and the intricacies of such an exotic weapon. You gain the following benefits:

• You gain a +1 bonus to attack rolls you make with a whip.
• When you hit with a melee attack using a whip you deal an additional 1d4 damage of whatever type the whip deals.
• While you are wielding a whip, other creatures provoke an opportunity attack from you when they enter your reach.
• • When you take the Attack action and attack with only a whip, you can use a bonus action to make a melee attack with another quick crack of the weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d4, and it deals the same damage type as the primary attack.
