I wonder why my "concussion weapons" and "parry" skills won't raise over a certain point... both of the red lines are _exactly_ the same length, they reach to the first letter "s" of word "concussion weapons" (sorry, I had no other way of expressing that)

I heard they should raise much higher... what's wrong, is it about the weapons I'm using? Should I use more advanced weapons to raise the skills? I am using only a dagger and no shield at all.
It's impossible for me to become a good warlock if my fighting skills won't raise anymore
