Well, gather info check takes 1d4 hours so feel free to do so :P. Then your not joining this fight this case. Also Elvas Imp arrives in round 10 as note. He send him fetch the assassin once it turned invisible.<br/><br/>Or you can go to site and roll search/spot checks and sense motive check if the controller or someone suspicious is near by the site and observing it too carefully or something. I give you fair 50% chance there is one.
