This skill is used for various situations: crafting, professions, and performing. Sometimes each of these uses intersects with each other. The DC list will be used to show DCs for crafting since Profession and Perform-based checks determine how high the quality is based on how high the result is.
Profession-based checks determine how much gold is made when a craft check is made. Take the result of the craft check and multiply it by 10. This can be done once a day, and counts as a day's worth of work (taking up at least 4 hours of time). This can serve as a side-job while the players aren't actively engaging in adventuring or heists. If you wish to reduce the time, reduce the gold by 20 for every hour reduced (to a minimum of 1 gold).
Profession-based checks determine how well you play an instrument, dance, sing, act, or other various acts. This can be used in place of Profession for making money.
This uses Smarts or Luck as an ability score.
