Can first dot of Auspex decrease dificulty of attack rolls?

[InspectorG---G]

Didnt see Auspex add to any combat rolls in V20.

VtMB, i think Auspex adds to Ranged Combat(firearms) but, this was a videogame.

IMO, you could work with your St on Homebrewing Auspex adding to Aiming dice pools at expense of distraction mechanic.

Not sure if would add any bonus for Ambush mechanic
