Usage: Used to make coin-based currencies through the use of various metals (usually silver and gold).
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.
Minting coins for 1 hour yields 4d4 coins if you succeed at a DC 20 check. For every 5 you beat the DC by you increase the amount of coins by 2d4. These coins belong to the country you're minting for (unless you own the currency and/or country) and taking coins from the mint is a crime punishable by death, and checks and balances normally exist to discover this.
Debase Coinage
Coins can attempt to be debased in order to cut their true value, allowing you to mint more coins but carries the risks of inflation, and (in a worst case scenario) hyperinflation and a depression. Debasing coinage up to 50% is a DC 30 Minting check, increasing the DC by 10 if you are attempting to debase the coinage by a rate of more than 50%.
If you succeed at debasing the currency, you and all of the nobility and rich population acquire 2d12 x the percentage it is debased (50% would be 1.5, 2% would be 1.02, and so on) and the price of all goods increase by 2d4 x the percentage it is debased. If the nobility discover this debasing and dislike it, there may just be a warrant for your head.
It is not recommended to allow players to perform this, as this can complicate a game
