If your goal is to become a Knight, you'll be starting off as a Warrior and may purchase any and all Warrior skills at Warrior cost until such time as you find a teacher in-play that will permit you subclass to Knight, at around 7th level. Just so you don't have to respend anything later, it might be a good idea to just stick with weapon skills, slays, and proficiencies until that time.

Since I am technically a "new" player and the Knight class is restricted to me until level 7, can I buy proficiencies and the like upon character creation, or since my intent is to be a knight, do I have to refrain from purchasing the skills?
Thanks
