So I am just trying to remember/find where and how you can raise your skills through dialog options with NPCs. An example would be Lucas in Arroyo, he can raise Unarmed to 55% (I think if below 40%, it will only raise it to that.) A second example is Jordan in Arroyo, he will raise your Melee by 10%. I know there are others, but I just can't recall them off the top of my head. Would anyone be willing to help me compile a list?
