Combat

You're a combat veteran. This is a useful trait because it allows you to join in on warfare and duels. While a higher combat won't win you a war instantly, it will let you make a better argument for you winning it. What's the difference between an S class in combat and an S class in your weapon? Well, besides the fact that any combat master would probably take weapons first, you apparently know how to better use the weapons you can't use.

Ranks:
S:You’re the one commanding the troops, you have more experience than anyone.

A:You’ve seen combat on various occasions.

B:You have fought a battle or two and are better than a simple greenhorn.

C:You have gotten into a few scuffs and learned from it.
