@Arakasi: Well, that's not a terrible thing, as it has a change to canceling any successful healing attempts.
Let's run some numbers. You're a Fusilier Paramedic facing off against an 0 wound Asura. You've got PH 10 and a knife.
You can wound on a crit (4.75% chance, the missing .25% being the Asura beating your crit with hers).
However, on a non-crit, if she passes her
CC, you can't wound (Dam 8 vs.
ARM 8). So she has to fail her
CC on 20% chance, and you have to pass your
CC (60% chance for a non crit), and then you have to wound on a 15% - which I make a 1.8% chance.
Sum total, 6.55%
... And for the Medikit, the Asura has to fail her roll on a 20% chance (because if she passes, she either wins or you beat her and she gets healed) and then you have to have stuffed up the medikit on a 45% chance.
Which I make a 9% chance of killing her, a 37% improvement. But It also has a 26% chance of healing her and making the whole thing worse.
However, I didn't pretend it was sensible in the first place.
