Attempting to enhance stones' quality.
Ability Score(s): Precision + Intuition
Usage: Used as a means to attempt to enhance the quality of gemstones, giving them a shine and glimmer that makes it look beautiful. Each gemstone you attempt to improve the quality of you must make a DC 30 check, and on a failure the gem is ruined and worth 1/4 its original price. On a success you cut the gem properly and it is able to be sold at an additional +25%. For every 5 you beat the DC by you increase the price by another 25%. Whether you succeed or fail, the gem can only be polished once, and can't be performed again.
It is used as an occupational skill and thus is either used to craft the desired good or attempt to make your wage with it. For each day you spend in a month working your profession, you make a DC 26 (+2 per additional day) check and for each success you have you increase your wage by 10%. Failures reduce your additional wages by 10% (to a minimum of 0% new wages or no increase to your wage). Typically a moderately successful character makes an additional 25% to 60% of their wage in additional money.
Cutting gems for 1 hour yields 1d6 polished gems if you succeed at a DC 20 check. For every 5 you beat the DC by you increase the amount of gems by 1d6+1. These gems are made up of formerly scuffed and raw earthen materials, and thus once made into gems they're counted as having already been polished. You can attempt to increase their value after waiting a week.
