Isawa shugenja get a Free Raise for all rituals.
Almost invariably, the Isawa send their children to the school - it is considered a great dishonor if an Isawa child is not accepted to the Academy of Wizardry. For the Shiba and the Asako, it is less an obligation, and more a simple test to decide the child's options for the future. 
Techniques
Because the tensai are taught as standard Isawa shugenja for the first few years of their training, they have full knowledge of the workings of the general spellcraft which is used by their companions in the Clan of the Phoenix. However, they have completely devoted themselves to their singular field of study, be it Earth, Air, Water, or Fire. Void tensai have their own ishiken school. 
In game terms, this means that tensai receive a Free Raise to any spells within their element for each School Rank. These raises may be used in any way the player chooses, whether for distance, damage, or accuracy, and may be divided as the player sees fit. 
However, such devoted training to one element is certain to leave a tensai somewhat lacking in knowledge of other elements. Although the tensai may still learn and cast spells of any element, it is more difficult for them to do so. Spells of all elements other than their primary have a +5 to their TN for every School Rank past the first the tensai has achieved.
