You have to look at the Prerequisites. Most, if there is a level and a class(sentinel etc)/Character(Bao Dur, Handmaiden, etc) it's nearly impossible that you have to invest a point or feat into this force or feat...it was the same with Kotor 1.

Just wanted to add this to the thread for those searching the archives, since I'd not come across specific character information (force power progression, skills per level, etc) in other threads, other than the feat progression and saving throws charts in the main sticky. The following is a walkthrough, so be warned for spoilers... might want to use Find in your browser and then search the Table of Contents for the specific sections, skipping the Characters and Walkthrough parts. Anyway, goto the following page and click on the Walkthrough by D. Simpson, which offers the most detail on character generation that I've come across so far...
