Sword Master

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

• When you take the Attack action and attack with only a Greatsword, Longsword, shortsword, Rapier, or Scimitar you can use a bonus action to make a melee attack with the opposite end of the weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d6, and it deals bludgeoning damage.
• While you are wielding a Greatsword, Longsword, Shortsword, Rapier or Scimitar, other creatures provoke an opportunity attack from you when they enter your reach.
• Before you make a melee attack with a Sword that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
