Berating Words

You realize your inspiring presence can have the reverse effect on a foe. At the expense of one majesty point and as a reaction to you or your ally being targeted by a weapon attack by an enemy within 60 feet of you, you can berate the foe and cause them to miss. 
As a use of one of your Inspiring Words die, you may add that result to you or your allies armor class against the creature's attack. You must decide to use this feature before the target rolls their attack, but once they've targeted you or an ally.
