Wait, what? Since when was Hlidskjalf his family's bloodline magic? Hlidskjalf was the magic Rose used when she saved him, the family's bloodline magic Chris used earlier in this fight was called Mystel Tainna. You could maybe make a point that Rose is secretly a previous member of his family, and so they're both using Hlidskjalf, but we also saw the chants that accompany both spells, and they're not the same.
