This will not end well...
I was running a vanilla World of Darkness campaign with a few of my friends who I regularly game with. One of my players who loves to break any system he plays decided to make a character who is seriously good at only one kind of attack.
The party is traveling down into a catacomb full of cultists. They massacre their way into a room with a large pit in the center that is impossible to see the bottom.
DM: Alright guys, there are carved reliefs colored with what looks like blood in different stages of drying and decay.
N: I could care less. What is in the pit?
DM: You can’t see the bottom.
N: ok I shoot into the pit.
DM: You… Ok, fine. Go for it.
N: *rolls 18 dice* I have 22 successes. I think I hit whatever is down there.
DM: You… I… What… *Facepalm* Yeah, you hit it. Everyone make a Resolve and Composure check.
N: Oh, should I not have done that?
J: This will not end well…
Needless to say this lead to a total party death when they took on half a dozen Shoggoth. In his defence he did kill two right off the bat.
