new spell for all casters what detects who has killed a monster and left its
body to raise as a undead... very usefull while ... idling...

I'd like undeads haunt their slayers more and care less about other players.
Since newbies mostly leave corpses around that haunting could be something non
lethal like interrupting camping with bad dreams of their victims, occasional
panic and flee at night because of ghosts only he can see, visions of murder
distracting concentration and lowering spellcasting skills... and maybe
somekinda exorcist spell to remove these or trip to the place where that
corpse was left rotting and praying for forgiveness there.
