Using this blessing allows you to fly into frenzied zeal, granting you a presence that some people may find unnerving. This blessing gives you a +2 bonus to your Charisma and Constitution score and a +2 bonus to your Charisma based skills. But, you take a -4 penalty to your AC and other skill checks. Using this blessing creates a strain on the mind and you become fatigued afterwards.
By channeling this Blessing as a Full Round action, the bonuses and penalties increase by 2 at the beginning of your next turn.
