Glorious Defense

15th-level Oath Of Glory Feature

You can turn defense into a sudden strike. When you or another creature you can see within 10 feet of you is hit by an attack roll, you can use your reaction to grant a bonus to the target's AC against that attack, potentially causing it to miss. The bonus equals your Charisma modifier (minimum of +1). If the attack misses, you can make one weapon attack against the attacker as part of this reaction, provided the attacker is within your weapon's range.

You can use this feature a number of times equal to your Charisma modifier (minimum of once), and you regain all expended uses when you finish a long rest.
