@DM_Zeppelin@Jackgiantkiller A sword can cut a mook's head off or run them through the heart in one hit, but heroes only get dramatic scratches on the cheek or arm. 1d8 damage! Enough to kill a 1HD character, but not a serious threat to a high level fighter.
Guns, on the other hand, give heroes a minor "graze" on the shoulder or leg, but BOOM HEADSHOT! to the nameless goons. Obviously, they need to do 3d12 damage with a X4 crit multiplier and cost 10,000gp plus 100gp per shot.
