Underground Mining (sage ability)

Underground Mining is an authority-status sage ability in the study of Geology, which describes a knowledge of mining techniques and skills associated with the excavation of hard and soft materials below the surface.

Those with the ability are able to detect the following within ten feet of their position when they are underground, when actively examining the rock or sniffing the air in a passage:

• Determining the grade or slope of the passage within 5° of its actual slope, as well as its direction of slope.
• Recognize new construction of a passage or tunnel, within a month of its probable origin, up to six months into the past.
• Determine the approximate depth underground, within 50 feet of the true depth.
