Thanks! My magus is only 3 years out of apprenticeship so this is not his business. But later could be interesting if our party will play so long.
This beautiful life is interesting, too. I suppose this is something similar I choosed to him earlier.
Jerbiton magi, being less focused on combat than other magi, do not have this idea that young magi are not ready to do significant things. A yuong magus is a -magus-. He should be out there doing cool stuff right from the beginning.
Especially having a cool focus. 
He must to concentrate being able to brew his first longevity potion.
His elder sodales didn't let him to important negotiations. 
Even he has the skill and affinity.
