Also some rewards go straight to the player rather than landing as a drop and may not even appear as a reward in the mob DB. Killing the Grim Reaper always gives the killer 20 keys and they aren't dropped. There are other drops like this, but are rare and seem to be used on special maps with bosses only, I *think*. I can't find the "Grim Reaper" in the monster DB and can't even find anything like it except the Reaper. This may simply be a reaper with a special name and the 20 key reward added.
