If you get the usual set up on someone, it's -20 to the opponents' actual resistance, then %, then flat penetration. Was buffed to this a little while ago, however, penetration does not exceed 0, so if you have more penetration than the target has resistance, you're doing true damage.

HOWEVER if you get their actual resistance below 0, you then start to do *more* damage than listed to them.
