Scorpios ATTACK = 8 >= 8 = William's Count. ATTACK, so William didn't managed to stop the targeted attack.
Scorpio will deal FULL DAMAGE and it will be ON TARGET.
Calculation is:
(4 x 10) + (2.5 x 10) + 15 (randomly got) + (2 x 10) = 100 points
To hit lower part of the body = 55, to hit crotch (I guess that's Williams private parts ) = 80, which Scorpio exceeded.
William suffers: full damage (50 points) + 20 points (due the Scorpios Good Foot Work perk) = 70 points of damage (but half of that is still lower than 50 points of personal HP that every precised organ has). So, no critical damage, just one big bruise.
William still have one, but I think you already know what card is that. ;]
Turn will be over, but conditions caused by last cards will transfer on turn two.
And you will have new cards to respond to those conditions.
