If gods/goddesses and demigods are immune to magic and the laws that govern it, shouldn’t they be immune to the rules that created immortals? Like wouldn’t a god/demigod be able to kill an original without needing the white oak stake as an example? Or maybe a tribrid without the red oak stake? I mean they predate the rules of nature and magic so in theory they should be able to kill anyone without needing a specific item and abiding by the rules.
