Roof building.
Ability Score(s): Common Sense
Usage: This is used to build, repair, and maintain roofing.
Repairing a roof requires a DC 30 check and repairs any holes or issues with the roof.
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.
Building roofs for 1 day yields 1 roof if you succeed at a DC 20 check. For every 5 you beat the DC by you can make more roofs (increasing by 1 each time).
