I'm not sure it actually *does* anything, over 127%, to Krell's point. If that's the case, then I should have just used 4 potions, plus my items, to hit 125% each time, rather than waste a potion for that last 2% (or waste 3 potions for it in my final assault). I don't have a good way to test this, other than by "feel". And I mean it simply felt like I was getting healed more when I drank potions that would get me secretly to 200%. Alternatively, could have been lucky rolls on the Field of Repulse, lucky rolls by the Golems to hit me harder, etc.
