Like
Craft,
Knowledge, and
Perform, Profession is actually a number of separate skills. You could have several Profession skills, each with its own ranks, each purchased as a separate skill. While a
Craft skill represents ability in creating or making an item, a Profession skill represents an aptitude in a vocation requiring a broader range of less specific
knowledge.
Check: You can practice your trade and make a decent living, earning about half your Profession
check result in gold pieces per week of dedicated work. You know how to use the tools of your trade, how to
perform the profession's daily tasks, how to supervise helpers, and how to handle common problems.
Try Again: Varies. An attempt to use a Profession skill to earn an income cannot be retried. You are stuck with whatever weekly wage your
check result brought you. Another
check may be made after a week to determine a new income for the next period of time. An attempt to accomplish some specific task can usually be retried.
