Artifacts

If you're getting confused by all the magical bits and bobs sprinkled throughout the books, here's a reference list for you!

Foe-Glass

Sees reflections of enemies, but only when you see the whites of their eyes are you in trouble.

Goblet of Fire

Used to select names for the tri-wizard cup. Appears to be a rough-hewn wooden cup, filled with blue-white flames. Placing your name in the Goblet constitutes a binding magical contract.

Invisibility Cloak

Makes the wearer invisible (doesn't work on Dementors or magic eyes)

Mad-Eye Moody's Magical Chest

One chest which is really seven different ones, depending on which keyhole you use to unlock it.

Magic Mirrors

Mirrors which show ordinary reflections, but also pass comment and give advice (of sorts).

Maurauder's Map

A piece of blank parchment, on which appears a map of Hogwarts when the words "I solemnly swear that I am up to no good" are uttered. It shows secret passages out of the school and the position of every person (and cat) in the building. Also insults anyone who tries to find out its secret.

Mirror of Erised

Shows the viewer what they want to see in their hearts. The inscription reads: Erised stra ehru oyt ube cafru oyt on wohsi

Translates to "I show not your face but your heart's desire"

Omnioculars

Binoculars that allow you to see in fast forward, slow motion, instant replay etc...

Put-Outer

Extinguishes electric lights when clicked. Resembles a cigarette lighter.

Penseive

A bowl to put excess thoughts in.

Quick Quotes Quill

An acid green quill which acts as a dictaphone, but writes down everything you say in true tacky tabloid style!

Remembrall

Glows red when you hold it in your hand if you've forgotten something. A fight with Malfoy over this ball is the reason for Harry becoming Gryffindor Seeker.

Secrecy Sensor

Vibrates if it detects concealment or lies. Can't be used in school ('cos all the pupils lie constantly)

Sorting Hat

Tests all new first-years to see which house they belong in. Given brains by the four founders of the school.

Sneakoscope

Spins, whines and lights up whenever anyone is doing anything sneaky.
