Could someone run me throught an example of a mage gaining attunement to the different convocations. I have looked at the rules, and after the study period the mage enters the game with the primary. Without use of a jorum mechanic, does he/she have to spend another x hours studing Arcane Discipline to be able to use spells from a new convocaton. Or is it just a matter of learning new spells in the different convocation???
