An Apprentice Witch/Witch Apprentice (Witchling in the dub) is a human girl or young witch studying to become a strong and powerful witch. In most cases, an Apprentice is not a full-blooded witch and is almost exclusively used to describe human girls. An apprentice has very weak magic compared to witches and will need the use of Pollon to cast magic until strong enough to just use her Crystal Ball. She can also return her mentor back to normal upon gaining strong enough magic if this is needed.
