Also it's a bit inconsistent with the rule book. In the book it refers to "light damage" but on the sheet it says "easy damage". I think you should use "light" and maybe call it "wounds". So for example if you roll a 6 for health you would get 6 light wounds, 3 average wounds and 2 severe wounds. I would even rename "average wounds" to something else like "serious wounds". Average sounds a bit strange when referring to wounds and damage.
