(Sai, you still have to roll the second defense, as if the difference is above or equal 12, it's a critical hit, doubling damage, and if for some reason it goes up to 18, x3 damage! So, you may end up not requiring the shock roll, that you missed by the way, since the 49 damage in one blow is above two time your shock value, giving a TN of 18. Not that I can put this kind of stunt easily, however... 2 turns, lose an action, -3 to -6 defense, -11 energy bare minimum, the opponent must stay close...)
