Greatsword Mastery

You have practised extensively in the use of the greatsword, gaining the following benefits:

• You gain a +1 bonus to attack rolls you make with the weapon.
  
  
• While you wield a greatsword, it counts as a reach weapon.
  
  
• On your turn, you can use your action to perform a defensive maneuver and start swinging your greatsword around your body to discourage attackers. Until the start of your next turn or until you're not holding the weapon, creatures who enter your reach with the greatsword must make a dexterity saving throw (DC 8 + your proficiency bonus + your Strength modifier) or take the weapon's damage and be pushed back 5 feet.
