Occult Slaying By default, the 'Occult Slaying' murders will be available against werewolf sims, however, if you don't have the werewolves gamepack installed or if you'd like to enable it against other types of sims you can enable them from the Extreme Violence -Mod- options category Extreme Violence -> Options -> Enable Occult Slaying For -> Select the sims that you want to enable the Occult Slaying against.
Feast On Neck Both of these murders will give your sim a harvested piece of flesh that will be placed in your sims inventory.
