Sword Master

You master the shortsword, longsword, scimitar and rapier. You gain the following benefits when using any of them:

• On your turn, you can use your reaction to assume a parrying stance, provided you have the weapon in hand. Doing so grants you a +1 bonus to your AC until the start of your next turn or until you’re not holding the weapon.
• Before you make a melee attack with a one-handed 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.
