I think that if Killmond had placed Vampires a little higher on the list
and acid blobs a little lower, his local score would be a little higher.
Acid blobs are cute, sweet, lovable and bring you up a level every time you
kill one in those first few crucial moments of the game.  Genociding rust
monsters should only be considered if you have a helmet.

Keep in mind that Nymphs can be very useful for removing cursed items.
