Greatsword Master

You can keep your enemies at bay with greatswords. You gain the following benefits:

• When you take the Attack action and attack with only a greatsword or a longsword while using both hands, you can use a bonus action to make a quick stabbing  melee attack with the tip 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 piercing damage.
• While you are wielding a greatsword or longsword using both hands, other creatures provoke an opportunity attack from you when they enter your reach.
