So, I was taking a closer look at some of my Templar's abilities (Purifying Light and Total Dark, specifically). First off, is the damage threshold on Purifying Light affected by just me or all group members? Second, can Total Dark be used on a dungeon boss? I ran City of Ash today and cleared it with little issue, however the Ash Titan fight would be so much nicer if this ability could be used to reflect back some of that aoe damage he's throwing out. I never even considered using it because it sounds almost like cheating if it actually does work. I mean someone could just span-cast Total Dark and defeat this guy and many others for that matter. Even though I have my doubts, I figured I'd ask here in case someone has tested this before.
