Blade Mastery

You master the shortsword, longsword, scimitar, rapier, and greatsword.
You gain the following benefits when using any of them:
• You gain a +1 bonus to attack rolls you make with the weapon.
• 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.
• When you make an opportunity attack with the weapon, you have advantage on the attack roll.
