Early this morning, Pottermore released the final chapters in Harry Potter and the Chamber of Secrets. J.K. Rowling’s free, interactive website for fans now has two complete books.

Here’s a breakdown of what is new. We did a similar breakdown for the previous chapter batch release and will continue these going forward.

Chapter 12: The Polyjuice Potion
– New material: Polyjuice Potion:

The Polyjuice Potion, which is a complex and time-consuming concoction, is best left to highly skilled witches and wizards. It enables the consumer to assume the physical appearance of another person, as long as they have first procured part of that individual’s body to add to the brew (this may be anything – toenail clippings, dandruff or worse – but it is most usual to use hair).

Chapter 13: The Very Secret Diary
– Nothing.

Chapter 14: Cornelius Fudge
– New material: Ghosts

Ghosts can pass through solid objects without causing damage to themselves or the material, but create disturbances in water, fire and air. The temperature drops in the immediate vicinity of a ghost, an effect intensified if many congregate in the same place. Their appearance can also turn flames blue. Should part or all of a ghost pass through a living creature, the latter will experience a freezing sensation as though they have been plunged into ice-cold water.

Chapter 15: Aragog
– “Find three spiders” — Ooh! For what? Nothing.
– “Keep the spiders at bay” mini game.

Chapter 16: The Chamber of Secrets
– New material: Chamber of Secrets

Perhaps, when he first constructed the Chamber, Slytherin wanted no more than a place in which to instruct his students in spells of which the other three founders may have disapproved (disagreements sprung up early around the teaching of the Dark Arts). However, it is clear by the very decoration of the Chamber that by the time Slytherin finished it he had developed grandiose ideas of his own importance to the school.

Chapter 17: The Heir of Slytherin
– New material: Chamber of Secrets

Successive headmasters and mistresses, not to mention a number of historians, searched the castle thoroughly many times over the centuries, each time concluding that the chamber was a myth. The reason for their failure was simple: none of them was a Parselmouth.

Chapter 18: Dobby’s Reward
– New material: The Sword of Gryffindor

The question of why a wizard would need a sword, though often asked, is easily answered. In the days before the International Statute of Secrecy, when wizards mingled freely with Muggles, they would use swords to defend themselves just as often as wands. Indeed, it was considered unsporting to use a wand against a Muggle sword (which is not to say it was never done). Many gifted wizards were also accomplished duellists in the conventional sense, Gryffindor among them.

We’re honestly appalled by how empty some of the chapters are, and the feverish level at which we’re required to search around a scene — sometimes for no reason. It gives us the early stages of carpal tunnel syndrome. With each new release of chapters, we’re shown how this overall concept was just not a good service to create. As we’ve stated before, the best and only good aspect of this site is the new material from Rowling.

If you need us, we’ll be resting our fingers after the fury of mindless, endless clicking.
