Trait Profession

Any profession that requires a person to have a formally recognizededucation in said profession. Without the Trait Certificate granting them the right to take their profession's title, they are not allowed to claim to be so.
It is forbidden to fake the certificate in any way and they are usually protected from replication by magical and other means. There are some professions that try to skirt around this, by choosing similar names - like the "Caprentristian Artisan" as opposed to the Carpenter.
