Specific Sensing Mechanisms
Creatures with blindsense or blindsight typically perceive using a specific sense mechanism, indicated in parentheses after blindsense or blindsight in the creature’s statistics. If this sense somehow becomes unusable, the creature loses access entirely to its blindsense or blindsight. The typical senses through which creatures can perceive are emotion, life, scent, sound, thought, and vibration.
Specific entries for blindsense, blindsight, and other senses can be found in Special Abilities beginning on page 262.
