Though some small Force abilities may be instinctive or learned from experience, to become a powerful Jedi you must train. Training with a Jedi Knight or Jedi Master is the fastest way to learn, but a Force user can also learn by himself through trial and error.
"I want to learn the ways of the Force and become a Jedi Knight like my father." - Luke Skywalker, A New Hope
"You will be trained as a Jedi, I swear It." - Obi-Wan Kenobi, The Phantom Menace
A student may improve with the Force more quickly if he trains with a Jedi Knight or Jedi Master that has a higher amount of Force Experience (FXP) than himself.
A Force-sensitive gains power in the Force by increasing their Force Experience level. Each Force Experience level will give one Force Skill Point (FSP). Each level requires (100 * ((n-1)*(n/2)))FXP to reach. E.g. Level 1 = 0 Level 2 = 100 Level 3 = 300 Level 4 = 600 Etc.
A Force-sensitive may train to try to increase their Force abilities. A student may train alone, with a teacher, or with a Holocron. The student chooses to train for 1 - 12 hours, and neither the student nor the teacher (if any) may move during this period. Training may be aborted at any time, and will also abort if either the teacher or student takes damage, or if either teacher or student is arrested.
At the end of the training session, the number of successful one-hour "chunks" of the training session is individually calculated. The Force-sensitive will gain 100 FXP for each successful hour. Aborted training will calculate successful training results for the last fully-completed hour.
For every 100 FXP earned, the Jedi will gain an additional Force-point in their pool.
FSP may be spent to increase any power when the Force-sensitive has enough. Force powers require the following amounts of FSP: Level 1: 1 pt Level 2: 1 pt Level 3: 2 pts Level 4: 3 pts Level 5: 4 pts. It would take 11 points in total to increase a skill from level 0 to level 5.
A Master is extremely experienced in the ways of the Force. A Knight or Master can function as a teacher. A Jedi trainee may have multiple teachers in their lives. A teacher knows many ways of drawing upon and controlling the Force, and can pass these on to the student.
Training with a teacher greatly increases the student's chances of learning about the Force. A successful training results in: 15 XP and 100 FXP for the student, and 5 XP and 25 FXP for the teacher.
Before the Master may invite an apprentice to learn the Force under them, the apprentice must add the Master as "Friendly" on their IFF list. A Master and his apprentice can leave each other at any time.
When training with a teacher, the student gains the benefits of the experience and insight which that teacher has to offer. The teacher knows what works and what doesn't. He knows a proven method of learning because he has already been a student. Without a teacher, a student is at a severe disadvantage. Everything the student does is through trial and error. Simply put, it takes much longer! The time taken per session is the same and the likelihood of success is 20% for a session. A successful training results in: 15 XP and 100 FXP.
