So the Winter Witch archetype says that it may not know or cast fire spells at all. But it also says that the Vengeance patron is one of the patrons a Winter Witch may select. But the Vengeance patron has two fire spells on its list which it gives the witch. Does a Winter Witch just lose those two spells know. Does it side step the no fire spells rule. Or do they change to no longer be fire?
