Harry Potter and the Half-Blood Prince

Level 19

[19.1] Go to the bird cage.

Investigate what Draco is up to in the seventh floor corridor


Harry takes the note from the cage and sees Ron walking in the corridor:
Hey, Ron! Have you seen Malfoy?



Harry: Just now. He’s always hanging around on this corridor. And I just found this. It looks like instructions for a Potion.
Ron: It’s probably homework.
Harry: And when has Malfoy put effort into homework?
Ron: Don’t even know it’s his.
Harry: I’m going to ask Hermione what this Potion is. I bet that will give us a clue to what Malfoy is up to.
Ron: You’re in luck. She’s swatting in Potions now. Careful, she’s still in a right mood.
Harry: So, you won’t come with me then?
Ron: I’d rather face that troll we saw in our first year. See you later.

Find Hermione in the Potions classroom


Before going there find all Mini-Crests and Hogwarts Crests. A Crest is found by hitting the banner. Turn around and hit the second banner, next the third and take your Crest.

Meet Hermione:
Hello, Hermione. Do you recognize this Potion?
Hermione: I’m surprised you don’t recognize it, seeing as you’re top in Potions. It’s obvious what this is.
Harry: So? What is it?

Why ask me? You should ask the Half-Blood Prince.


Harry: All right, I will. Well, I can make the Potion and find out anyway.

Then you’ll see the Cauldron: Mystery Potion. Harry says:

Shredded Boomslang skin...


Take one Boomslang skin, dry until... dry, then shred.
[NOTE: “Boomslang” is Afrikaans/Dutch meaning “Tree Snake”]
