Well as far as I understood about choosing skills is this:
Manouver Skills: 2 points in rigid leather.
Weapon skills: 1point on One-Hand, 1 point in Two-hand and 1 point in Missile weapons.
General Skills: 1 in Ride, 1 in swin and 1 in Track.
Subterfuge Skills: 1 point for each.
I guess that's it for an adventurer, hope it's alright 😉
