Felix Felicis

"It's liquid luck ...It makes you lucky!"
-- Hermione Granger (HBP9)

"Mine own invention, my masterpiece; the crowning achievement of my career. Bottled good fortune. Brewed correctly the drinker of this potion will be lucky in all their endeavours ..."
-- Zygmunt Budge (BoP)

Felix Felicis

Felix Felicis is a potion sometimes called “Liquid Luck.” Until the effects wear off, all the drinker’s endeavours will tend to succeed (HBP9). Once consumed, the potion gives the drinker an exhilarating sense of confidence and a tremendous sense of opportunity (HBP22). However, if taken in excess the potion causes giddiness, recklessness, and dangerous overconfidence, and it is highly toxic in large quantities (HBP9).

  • Not brewed in class, but used as a reward from Professor Horace Slughorn in 6th year (HBP9)
  • Colour of molten gold; while exposed to air large drops will leap like goldfish above the surface without spilling (HBP9).
  • A "miniscule" glass bottle can contain enough Felix Felicis to last 12 hours (HBP9).
  • The potion is a banned substance in organized competitions such as sporting events, examinations, or elections (HBP9). According to Zygmunt Budge, it is only allowed during potions tournaments (BoP).
  • Desperately tricky to make and disastrous to get wrong (HBP9).
  • Harry consumed one mouthful of Felix Felicis on the night of Aragog's burial which helped him convince Slughorn to turn over his true memory of Tom Riddle asking about Horcruxes (HBP22).
  • It takes six months to brew (HBP24).
  • Harry turned over the rest of his supply of Felix Felicis to Ron, Hermione, and Ginny on the night he and Dumbledore left Hogwarts to try to retrieve the locket Horcrux (HBP25).



"felix" L. lucky + "felicis" L. lucky (same word, differently declined); Felixempra: "felix" L. lucky + "sempra" L. always, forever


In the movie production of Half Blood Prince Felix Felicis is portrayed as a clear liquid, not a molten golden substance as is described in the book.

Harry would never have won the Felix Felicis without the Prince's copy of Advanced Potion-Making. Severus Snapes corrections and notations were essential to Harry's victory. Another bullet point on the list of acts that Snape did to help bring down Voldemort, for without the liquid luck Harry may never have been able to obtain the crucial untainted memory from Slughorn. --EJ
