what potion did harry potter take to get slughorn's memories
Potions in Harry Potter Felix Felicis, more commonly known as Liquid Luck, grants whoever drinks it unusually good luck.[1] The time span of this luck depends on the amount imbibed. Liquid Luck is one of the hardest potions to make, as noted by Horace Slughorn; "It has to be cooked for 6 months on an extremely complicated formula, and if you make a tiniest mistake, the consequences are severe". Because of its properties, it is banned in all sporting events, competitions and examinations. In Rowling's original narrative, the potion looks akin to liquid gold. However, in the movie adaptation it is clear and water-like. Slughorn also noted that excessive consumption results in side effects that include giddiness and overzealousness, among other effects that are related to overconfidence. In Half-Blood Prince, Harry pretends to give some to Ron so that he will do well at Quidditch. Ron's luck turns for the better, with the confidence working as a placebo. Harry does use most of it later in the same novel in order to extract the true memory about Tom Riddle and Horcruxes from Slughorn (though it also has the pleasant side effect of causing Dean Thomas and Ginny Weasley to end their relationship), and the rest is shared between Ron, Hermione, Neville Longbottom and Ginny the night Death Eaters break into Hogwarts.
Severus Snape In Harry Potter and the Deathly Hallows, Voldemort and his Death Eaters have tightened their grip on the wizarding world. Snape is named Headmaster of Hogwarts, while Death Eaters Alecto and Amycus Carrow are appointed as Hogwarts staff. The novel focuses largely on Harry and his friends and events outside the school; therefore Snape plays a limited role at the start. In the course of the book, Harry and his friends find out that a few students attempted to steal the Sword of Godric Gryffindor, and that Snape subsequently sent it to be stored at Gringotts Wizarding Bank; however, that sword was only a copy. Later on, Harry and Ron are led to find the real sword by a Patronus taking the form of a doe.[39] (Towards the end of the book, Harry learns that this was Snape's Patronus, taking the same shape as Harry's mother Lily's Patronus, a visible sign of his lifelong love for Harry's mother, and that Dumbledore had asked Snape to ensure that Harry gained possession of the sword.[40] The novel also reveals that Snape had covertly used his position as Headmaster to protect the students and to contain the Carrows.[40])
