I've been playing Iron Kingdoms as a player for a few months now and one thing I have found is that it is incredibly difficult to finish off a player (or a NPC who the GM has decided to make use the injury table). It seems that you can survive for a long time while on 0 hit points. Our group has an Ogrun who is frequently 'dropped' in the first round of combat, but every time he rolls on the injury table, gets results like 'Horrific Scarring', which don't even take him out of the fight. Sometimes, the situation becomes farcical, such as when a group of people gang up on the villain who just won't die despite rolling 4 or 5 injury rolls per round.
So my question is this: Is there a way to make the injury table more lethal, or progressively worse the more you roll on it? Or are we doing thing wrong in some way?
