Skill and Feat Training
As your character advances through the levels they will gain more skills and feats to make them more powerful. In our game these are not just bestowed upon your PC, they must seek and go through training for whatever skill or feat they are trying to gain.
These will sometimes cost money, services or time to achieve. If you simply add more ranks to already owned skills or feats training is not needed unless the GM deems it to be (usually because you haven’t used this skill enough).
Class Features that you gain as your Character advances are automatic as they are basically the result of your Character having used their skills more and more.
