To add to this general discussion.. I too have seen the fabled 30% Damage increase if not hit for 5 seconds bonus from the Fade-Touched Varghest Scales. I have ALSO been farming said varghests. I am seriously concerned as to why this is the only crafting material that has FOUR possibilities, wherever you look online and even in the strategy guide. You either get 20% Damage, or 10% Chance of Immolate at 75% Damage, OORR you get 30% Damage, or Immolate at 100% Damage. I have farmed a total of 7 Fade-Touched Varghest Scales, 4 of which are 20% damage, 3 of which are Immolate at 75% Damage. Until I see a screenshot otherwise, I don't even believe that the 30% Damage, or Immolate at 100% Damage even exist. Also, out of the two spawn locations for varghests (South by the Dragon, or way north on the other side of the darkspawn cave) I've had more luck at the north spot.
