The rules of the Death Note heavily influence the strategies employed by its users. For example, users must know the target's full name and face to write their name in the Death Note. This requirement affects how users gather information about potential victims and can lead to elaborate schemes to ensure they have accurate details. Additionally, the rule that a user will die if they don't write a name in the Death Note for 13 days pushes users to maintain a consistent killing schedule and manipulate events to avoid suspicion. Overall, the rules of the Death Note shape the tactics and methods used by its users in carrying out their intentions.
