You are able to scry on your summoned shadow companion for a limited duration each day.
Benefit: For a total duration of 1 minute per day per level of shadowdancer you possess, you are able to scry on your summoned shadow companion (as with the scrying spell). Your companion forgoes making its saving throw, except that if your shadow companion is within a dimly lit area the range of your senses beyond the shadow increases by 50%. Your caster level is equal to your shadowdancer level.
