Power level is your status in the game, its not your health, or anything. Its how powerful you are and how much ki you have.
How to gain power level:
- Battling (See battling guide about PLs)
- Quests (There will display the amount of PL rewarded for a quest.)
- Sagas (Same as quests)
- Roleplaying/Training (Mods/admins will come up with a whole system behind the PL for training/roleplaying.)
