While cleaning out my vault of duplicates, I came across a piece of armor that had "Heroic Resistance" instead of the usual "Void", "Ark", "Solar" Damage Resistance. It isn't on a particularly good piece of gear (not one I would want to wear with my current setup anyway). Tried to find info on it via Youtube, Google, Reddit already but couldn't nail down an answer yet. So if anyone here could tell me definitively what it does (with proof and not just an assumption) that would be great.
