Typical that'd id look at this while im on my desktop...and my files for this are on my laptop 1) Neutral Power - Anyone can use it. 3
2) Dark power obviously - Apostle level min 3
3) Neutral Power - Knight/Apostle Level 6
4) Dark Power - Apprentice Level 8
5) Dark Power - Apprentice Level 12
Training-wise....A certain number of sessions with the holocron at least since holocrons don't hand out all their info at once. The red numbers would be my recommended number of posts by the person looking to aquire these powers but they may be a bit low. Also it'd be kinda a give take. Person posts and moderator responds accordingly.
Also there should be a time period inbetween learning the powers. 2-4 weeks?
