Every time a character gains a new level, make a Profession check. (If the character has no ranks in the
skill, this check is a Wisdom check.) The DC is equal to the character's current
Wealth bonus. If the character succeeds, his or her current
Wealth bonus increases by +1. For every 5 points by which the character exceeds the DC, he or she gains an additional +1 to his or her
Wealth bonus.
