I already succeded in knocking someone unconscious, just like Fedaykin describes. A friend of Hagen was possessed and was just struggeling with his own mind ((if you know what i mean with that,,,my eng could be better i know

)) so i hit him with a shovel (g*). But you will have to rely on the other player to react accordingly. Hagens buddy just typed #me falls down unconsciouss. He could also have written #me spins around and kicks the shovel out of Hagens hands, sensing the surprise attack.
Some people seem not to like it if you force them to take drawbacks only because of what you roleplayed. Well i think it interesting and most funny to let my char suffer certain drawbacks, when someone creates a plausible story. Hagen already got tied and almost thrown in the river and today was the 8th time someone tricked me and stole my money. ((he really cant handle the money, this Hagen

))
To sumarize this,,,EXPECT EVERYTHING,,,some will simply ignore you some will be making suspicious moves and some will simply react how you expected them to do.
