Disposition modifiers to Holy Radiance

Can't seem to find anywhere the actual modifiers for Holy Radiance regarding the priest's disposition. Trying to decide if I want to pick up Untroubled Faith or not. Not a big deal, as I picked up Aggrandizing Radiance, so I only tend to use it when I need that extra push in a fight or I end up in melee, but I was just curious on the breakdown of disposition modifier, as I don't see it listed explicitly anywhere. (this is for latest version, white march 1&2)
