Working Overtime

If you are working longer than 8 hours per day on creating a magic item/scroll, you must make a Wisdom Saving Throw every 2 hours beyond the initial 8. The DC starts at 10, and increases by 2 for every 2 additional hours of work. For example, working for 12 hours would mean a DC12 Wisdom Saving Throw, and working for 16 hours would mean a DC16 Wisdom Saving Throw. On a failed save, the character takes a level of exhaustion and cannot continue working that day.
