Is there a potion that can be done only 의해 purebloods?

Why would such an potion even exist??????
No idea, seriously, but I don't think it exists...

i highly doubt it. unles if they were transfering genes 또는 something. because if 당신 take malfoy and hermine, malfoy says that she is a mudblood because she doesnt have parents that are wizards, and Dracos does. besides the fact that draco is a stuck up snob, they arent that different. so i dont think that there is a potion that can only be drinken 의해 purebloods.

no it doesn't exist sth like that... all the wizards and witches are equal and it doesn't matter at all which their blood statue is...

If it did exist, I imagine it would be very dark magic, but I don't think it does. The reason I don't think it does, though, is because it would go against the whole message (or one of them) of JK Rowling's story: That one is defined 의해 one's actions, not 의해 one's lineage.

I don't really know. That's really something to think about. I think as long as 당신 have a wand and have gone to a magic school, 당신 can do anything magic throws at you.

i don't think so
hermione can concoct everything^^
