Sword Master

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

• When you take the Attack action and attack with only a longsword, shortsword, greatsword, or rapier, you can use a bonus action to make a second melee attack with 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 slashing damage.
• While you are wielding a longsword, shortsword, greatsword, or rapier, other creatures provoke an opportunity attack from you when they enter your reach.
• You gain proficiency in these specific weapons.
