what about some kind of initial traits like ‘Blunt affinity’ or Blade affinity’? I personally, while knowing how to use and defend against them, dislike bladed weapons and prefer blunt weapons. If SHTF, I actually have a a 16" white wax-wood club with riveted studs and a wrapped grip that I made that would be my go-to over even the most expensive blade. It would be nice to be able to have that reflected in a character without necessarily having to spend 3 points on a martials arts weapon skill.
Blunt/Blade/Fist affinity- You deal slightly more damage and are slightly more accurate when wielding your preferred weapon type.
something like +20% to-hit chance and +20% damage done when wielding your preferred weapon type.
you wouldn’t get any extra ‘special moves or attacks’ but this would help reflect your personal preferences.
