Hi Mograg!
Thank you so much for the support and feedback.
When spending experience points, if a player rolls higher than their character's current percentage (extreme), that skill increases by 1 point.
Regarding weapon damage: Hit points are typically low (averaging 10.5), so it usually takes about two to three regular blows/shots to eliminate a character. However, you are absolutely correct: following the rules as written, it's very difficult to kill a character in a single blow/shot. The player would need to roll well and score a critical hit to double the damage.
In my games, I don't even require a roll if a character is shooting or slashing another at point-blank with the target at their mercy and the intent to kill. As for accidental discharge, I would probably use the Luck skill.
I'll definitely give this some thought and see if an increase in the damage bonus of the weapons is a good idea.
Again, thanks a lot for the help!
