Potions
Pewter
This charm, which Harry learned from the Half-Blood Prince, cases an unidentifiable buzzing sound to fill the ears of those nearby.
In Professor Lupin's class, Harry studied this creature, a water demon that dwells at the bottoms of lakes. This same creature is also how Lupin confirms Harry's identity after the Battle of the Seven Potters in Book 7.
Grindylow
This not very wizard-friendly centaur often disapproved of Firenze's actions.
Bane
"Stand and fight, you mangy cur!"
Sir Cadogan
This truth-telling potion was favored by Dolores Umbridge, but it was also used by Dumbledore in Book 4 to interrogate fake Mad-Eye.
Veritaserum
This silly jinx is fairly harmless, as it merely causes the victim to begin dancing uncontrollably.
Tarantallegra
This magical beast with a long snout is attracted to shiny things.
Niffler
This conductor of the Knight Bus was later accused of being a Death Eater.
Stan Shunpike
"You're just as sane as I am."
Luna Lovegood
DAILY
DOUBLE
Amortentia doesn't create true love but rather a powerful infatuation, and the potion smells different to everyone. Hermione smells these two things.
This healing charm is a quick fix for a broken nose.
Episkey
Hagrid created this creature, a highly dangerous cross between manticores and fire crabs.
Blast-ended skrewt
Millicent Bulstrode
"It unscrews the other way."
Lupin depends on this potion, which alleviates the symptoms of, but does not cure, lycanthropy.
Wolfsbane Potion
Levicorpus causes the victim to be hoisted into the air by their ankle. This counter-jinx will let the victim back down.
Liberacorpus
Hermione tried to inform Xenophilius Lovegood that the horn on display in his home actually came from this dangerous animal, not a crumple-horned snorcack.
Erumpent
She is the proprietor of The Three Broomsticks in Hogsmeade.
Madam Rosmerta
Harry Potter
[Nettle] Wine
To access the secret passage to Honeydukes, one must tap the one-eyed witch statue and say this incantation.
Dissendium
After the hippogriff Incident, Hagrid (lacking confidence) spent most of the following classes on this boring creature. In fact, his final exam consisted of simply keeping one of them alive for an hour.
Flobberworm
Ron impersonated this Magical Maintenance employee during the Ministry break-in in Book 7.
Reginald Cattermole
"Once again, you show all the sensitivity of a blunt axe."
Nearly Headless Nick
