Tremorsense (Universal Monster Rule)

This is a Universal Monster Rule — a class feature gained through that class's own talent choices, not a feat you pick through normal feat selection.

A creature with tremorsense is sensitive to vibrations in the ground and can automatically pinpoint the location of anything that is in contact with the ground and within range of its tremorsense ability. If the creature lacks the earth or aquatic subtype, it must remain in contact with the ground or the water in order to use this ability. Aquatic creatures with tremorsense can also sense the location of creatures moving through water within range.
