The cleric's armor of faith buff says it adds 0 armor. Is this a bug? I have 80 abjuration so it should add something. Also, resolution already buffs armor, so why have 2 armor buffs?

Armor of faith specializes in buffing armor. This must be some kind of bug. I'll check on it tonight. It buffs way more than valor. So basically it's just a mega armor buff for clerics.

Okay good deal. Using armor of faith does not increase my armor on the character sheet, so I can confirm that's a skill issue and not a tooltip issue, if that helps any. The talent that improves armor of faith does add its bonuses to the skill however.
