Well in all fairness the light novels, not even highschool dxd zero, haven't really made a good effort to reveal what the clan power of the lucifuge clan. And since serafall and grayfia fought in the devil civil war, both fought for the leviathan position, the o.g. leviathans specialized in water magic, and serafall is a master of ice magic which is a form of water, naturally people in fanfics assume grayfia's powers revolve around ice magic.
