Earth Sense is an Elemental Sense which is a Super Sensory capability that reads an area or event (not an entity) through filters of perception and understanding – either conscious or innate faculties. The character is able to sense the properties and qualities of an area of earth and stone, as well as understand events witnessed or exposed to that are related to it. without appropriate scientific knowledge, results cannot be expressed in such terms, though an intuitive sense of relative information can be gained. Note that it is inexact. It cannot be used for precise way-finding or address specific safety concerns without significantly increased time and exposure; Such investigatory measures can detect precise depth/height, hidden/concealed doors, gain Advantage on checks (or perhaps acquire one if none is allowed) to resist related dangers moving through an area (though such benefits only benefit the character themselves),

• The depth/height of the character under or above the surface level
• The position of the character under the earth
• The safety and danger of instability of an area
• The presence of materials constrained, divided or made impure/tainted/unusable
• The grade or slope of an area
• Current location under earth relative to surface (requires surface geography)
• The strength of natural elemental events
• The proximity of obscured alterations to natural materials
• The presence and volume/density of related materials
• The type and general amount of a related material
• The presence of life forms (rough; less than 10/more than 100) within a given area of related materials
• The amount of traffic the area has (rough; less than 100/more than 1000)

By default, the use of this sense requires 3 rounds of uninterrupted Concentration. The rough numbers can be improved if the character has deep locale familiarity and/or gain Advantage if the character uses a 3 full minutes of Concentration (as an Investigate activity).
