I have an enlarged wizard that wishes to use hand of the apprentice. Does the weapon remain in possession of the wizard and not revert to its original size?
Hand of Apprentice says “This attack is treated as a ranged attack with a thrown weapon, …” so with that in mind I would go with again the weapon would revert to its original size. No difference than a arrow fired from a bow would. My above is based on this line from the enlarge person spell: “Any enlarged item that leaves an enlarged creature’s possession (including a projectile or thrown weapon) instantly returns to its normal size.
