Effect	The caster gains the ability to sense movement related vibrations transferred through solid materials that the caster is in contact with. Typically used to sense movement on the ground that the caster is also standing on, a creative caster may use it to sense movement through a building by touching a wall. The caster knows the general direction, distance, and severity of movement, however these details may be distorted if the vibrations have to pass through multiple bends. A continuous path of solid material is required between the caster and the movement for the caster to sense it. For example, someone floating an inch above the floor wouldn't be transmitting any vibrations to a nearby sensing caster. This allows the caster a fine degree of sensation for movement near them including stealthy or invisible targets. Targets who are magically concealed using a method which does not disrupt their movements (e.g. Invisibility) do not get an opposed roll to avoid detection by Tremorsense.
