When you look at an npc's stat screen, they have will sometimes spawn with points in combat, firearms, or survivalist, which is not a skill we have points in but a skill category. I thought this may mean that they have that number in all the covered skills of that group, but I've found npcs with a 2 in combat but 1 in specific weapon skills, or 2 in firearms but nothing in aiming. Anyone know how that works?
