The caster alters their normal sense of smell, significantly improving their ability to detect faint scents given off by creatures in their immediate vicinity. Creatures within 30ft (9m) of the caster can be detected whether or not they can be seen. Precise location of the detected creatures is not possible, but general direction can be discerned.
Scents can be blocked by any solid, unbroken surface, but something as small as a keyhole or door seam is enough to permit the effect to work. Normal wind currents do not affect the ability, but various magic spells may (see their spell explanations).
Furthermore, if the creature is of a species or parentage that the caster has encountered in the past, the caster is able to identify the species or parentage.
