This talisman is designed by an Evil God that wanted his enemies to hear the death cries of all the heroes and monsters that his War Prophet has slain. To do so, he has captured their voices in their final moments and sealed them away in a special orb. The orb was then affixed to a handle made from the long bones of a slain Sycophantom.
To operate the Death Rattle, the hero violently shakes the talisman and utter the words "The ☾reato✔ has spoken". These words seem to awaken the voices within the cursed orb as they release their pent up hatred, pain and frustrations. The blood-chilling screams and wailing from the fallen heroes and monsters are extremely effective in plunging the opponent into unknowable depths of despair thus lowering his defences and sapping his will to fight as he is filled with visions of his death. The Death Rattle grows stronger, louder and more effective the more enemies the hero has slain. This makes the Death Rattle a top notch purchase and a long-term investment. Resale value of any Death Rattle is extremely high due to its ability to grow more powerful with use.
The heroes who use the Death Rattle often find themselves unable to sleep as the screaming coming from it are never truly silenced. You can spot a hero who is using the talisman simply from the dark rings around his eyes and his vacant stare as the voices of the slain continue to haunt him long after their deaths. Heroes who use this talisman are often more easily influenced to the dark side. Heroes are to use it with extreme caution.
