I'm playing it currently and thus far it has been awesome, BUT I've reached a point where as Louis Grunewald I'm on board the ship at the very first day traveling to Athens, Greece . A steward came to room and attacked me. Since the only thing I cheated in this adventure is that I pulped the investigators, I'm like the hell with it, I'm gonna stand my ground and try to blow his head off. He fumbled his first attack and I regular succeeded in mine, scoring 6 damage. I'm just trying to figure out how much hit points he has but I can't find any information in the adventure. Is every combat in this adventure with assumed hit points, until I say "OK pal, I think you got enough and (drum-roll) you're dead"? In the adventure it is stated "Otherwise, combat continues until either you or he is dead, or if he suffers the loss of half or more of his hit points and becomes incapacitated". How to reduce hit points when there are no starting hit points to begin with? All that is provided are his Dex, his Fighting/Brawl/knife skill at 50/25/10 and knife damage of 1d6. My only choice is to run and that sucks. Am I missing something? The path for the entries I followed is: 187/73/167/47/91/10/stuck Any insight would be much appreciated
