Always looking for the craziest turns, i thought that sometimes you need this player out of the way, so you need the odd to get rid of him (or not if you are in a chainpush puzzle).
So the armor and injury rolls are implemented, you can just add the armor to pass, and the injury you want to have and keep on with the sequence.

Of course, next skills implementation will be mighty blow and piling on.
