Would it be possible to change the good old "Blablah is DEAD, R.I.P." to say
"You cackle with glee as Blablah dies by the hands of you(r party)" or
whatever message which reflects that you're the "owner" of Blablah's corpse?
Oh I remember the days when you joined automatically to the battle if
you stayed too long in the same room with somebody else fighting a
(non-aggressive) monster.
