Drosco vs a Zombie
 

I can get Drosco to spawn, but I don't ever see "a Zombie." Are there two different mobs?

Drosco will eventually drop the medal. took me about 7 tries as in 7 Droscos.

I assume your doing the evil version of the quest? I spent a lot of time down there when I first started and I never saw a zombie.

Yes, I'm doing the evil side. I've killed Drosco who conned amiable to me, and he dropped the metal, but no note.
