Martial Disciplines

Martial Disciplines are rewards generally given to martial characters that can usually be taught by a teacher, learnt from observing a user, from an old manuscript, or through magical means. These are generally abilities that reward fighting in a certain way, and thus, you should not give any Discipline to any character, as it could clash with the character's play style.
