Defensive Duelist (Expanded Rework)

You’ve learned to deftly parry attacks, granting you the following benefits:

• Ability Score Increase. Increase your Dexterity score by 1, to a maximum of 20.
• Parry. If you are holding a Finesse Weapon and another creature hits you with a weapon attack, you can use your Reaction to add your Proficiency Bonus to your Armor Class until the start of your next turn, potentially causing attacks to miss you. For each attack that successfully hits you, this AC bonus decreases by 1 to a minimum of 0.
