If you attack from hiding, using a bow, you "give away your location", but to who? Certainly to your target (unless they're dead), but to anyone else? When your target goes down any other enemy standing next to him certainly notices it and has some idea where the arrow came from but is it exact? What about an enemy who is 15' away from the newly dead creature?
Would the DM just make a decision each time based on how close the enemy was to the target and how alert he was?
