Disciplines
Magical Disciplines are highly specialized knowledge about a certain type
of magic. Easy or basic spells usually don't require such a knowledge.
Now how can they be attained? The easiest way is to get yourself a
Grimoire and begin to
explore the world. Usually they are hidden in mystic places or are rewards
for dangerous quests.
If you found one, you'll automatically write
it into your grimoire. By reading your grimoire you can find out what you
already got.
