This is probably another of my dumb questions but the answer ain't popped into my head yet (oh, found half of it on a re-read:)
Target falls onto his skull. His helmet is DR16 and he suffers 15 damage from the fall. That's 3 points of Blunt Trauma. His innate skull DR stops 2 points. Am I wrong to apply the Brain injury wound multiplier to the remaining damage? (B399 "Exception: None of these effects apply to toxic damage.")

If he has an armoured skull, DR16, that would be innate DR and block all damage, yes?
