But not every demigods sets a full range of their godly parents abilities. I mean not every child of Apollo is able to see into the future (or summon a plague). Dionysus' kids were able to control grape vines, but they were never shown to be able to control madness. Leo is the only demigod child of Hephaestus with fire power.
