I changed the line to look like this:

 if (($itemcount{8911} == 1)&&($class eq = "Shadowknight")) {
  quest::say("Very good, but maybe you should keep this. I believe you will have more use for it than I. Maybe Dsarrik can help you.");
  quest::exp(10000);
  quest::summonitem("8911");
 }
 elsif ($itemcount{8911} == 1) {
  quest::say("Well now look at that! I believe you, $name, have done a great deed this day!");
  quest::exp(10000);
 }
}

And now I'm not getting a response at all when I do the turn in, shadowknight or otherwise. For the other quest mob involved, I changed it as well and he won't even respond to hails.
