The Savage interaction is only available to werewolves. Once initiated, the werewolf attacks the non-werewolf, initiating a fight. During the fight, lycanthrophy is transferred to the victim. If not close friends or lovers, the victim will become furious at the attacker. If they are close friends or lovers, the attacker will gain relationship points, and the victim will lose relationship points. If a werewolf from another family is on on the player's lot, they can influence them to fight with another Sim, like any other Sim can be influenced this way. However, because the player has influenced a werewolf, it will count as a savage, and thus turning the Sim they wanted the werewolf to fight with into a werewolf themself.
