Senses, Extraordinary

Blindsight: within its given range, a creature with Blindsight fights and maneuvers as well as a sighted creature in full light. Makes creatures immune to gaze attacks, and ignore invisibility, darkness, and most kinds of concealment. Must have line of effect to a creature to detect it. Blindsight doesn’t distinguish color and you can’t read. Deafness may blind creatures with Blindsight if it relies on sound. It works underwater but not in a vacuum.
Blindsense: blindsense allows a creature to notice creatures and objects it can’t see but not with the precision of Blindsight. Must still have line of effect and things that affect visibility effect blindsense. The creature can pinpoint location but still has total concealment and still denied AC against a creature it can’t see.
Darkvision: Darkvision is the ability to see with no light source out to the given range. They can’t see colors but light does not spoil it. Darkvision doesn’t reveal hidden or invisible things and doesn’t protect against gaze attacks.
Low light vision: such creatures can see twice as well in dim light.
Scent: a creature with scent can detect and track creatures by scent of smell and identify familiar odors. It can detect the presence of a creature but not its specific location. The range is usually 30 feet (15 if upwind). If it moves within 5’ of the creature it pinpoints its location. Tremorsense: a creature is sensitive to vibrations in the ground. It can pin point any creature within range that is touching the ground and not totally still. Aquatic creatures with tremorsense can feel vibrations through the water.
