Mastery and Skill are the exp of this roleplay. They both help you win fights and be more sneaky. As an apprentice and a kit you have something called skill. This is what you earn before it gets converted into mastery. Skill can be earned in many ways, here are the amounts. » Kits +1 for playing any game +1 for learning about powers from a cat with powers +2 for touching a marking trait (3 times a week max) +4 for sneaking out of camp (must be rolled) » Apprentices +1 for learning about powers +3 for learning from your mentor +3 for learning about powers from the opposite clan » Warriors +1 for using powers (or if medic, healing someone) +1 for training an apprentice Once an apprentice becomes a warrior, the skill they earned will become mastery. This will slowly build up until you can use more powerful moves. The leader skill can only be used by the leader, regardless of mastery level. I wish you luck in your adventures!
