All I can say is, don't get immobilised or made helpless. Heres a breakdown.
Corporal: melee -2 whip (1d3, 10/0) [+2 bab, +0 str, non-proficient.]
Nate: Soak 2, Defense 0* [immoblised, Automatic Defense roll 1).
* Technically, -3 (Imobilised: Dex=0, -5 dex mod). But 0 seemed adequet.
Attack Rolls: 16, 6, 7, 14, 2, 15.
Damage (weapon + magin of success - soak): 3+11-2, 2+1-2, 3+2-2, 1+9-2, 2+10-2.
The first stroke would leave Nate Jarred, so the second, the third Staggered, the fourth Unconscious. Total non-damage: 34.
Three quarters of an hour later, Nate is up and dancing with the young ladies at the tavern. (Non-lethal damage recovers at 1 pip/minute of rest.)
Interesting.
I think that the first, fourth and sixth strokes should have done some damage. Perhaps 1 lethal wound. For colour.
Actually, it seems that the whip is probably not the right weapon for this. Oh well, it will do. Hopefully I'm not going to have to do this too often.
