Sphere: Scout

Creatures using unusual forms of sensory perception such as blindsight, greensight, or tremorsense cannot automatically foil your use of Stealth; such creatures must make a Perception check as normal to detect you when you make use of the Stealth skill.

Lurker foils divination spells and Divination sphere sense abilities in the manner described above, but has no effect on spell, sphere, spell-like, or supernatural abilities specifically used to uncover information about you rather than enhancing the user’s perception, such as when scrying or using the Divination sphere‘s divine abilities.
