"This isn't an ordinary potion," Will said. "It's an extremely toxic magical concoction, and it takes a specific method to neutralize it. If we drink it outright, we could hallucinate—or suffer something even worse."
Will knew exactly what it was. This extraordinarily complex potion forced anyone who drank it to endure agonizing hallucinations and relive their deepest fears and regrets. Voldemort had used it to protect his Horcrux.
"Without a doubt," Dumbledore said, nodding. "This potion is meant to stop anyone from obtaining the Horcrux. It might paralyze me, make me forget why I came here, cause such intense pain that I can't concentrate, or incapacitate me in some other way."
In the original timeline, Dumbledore had drunk the potion and suffered greatly for it.
Could something like this be turned into a spell? Will wondered.
Dumbledore had no idea what Will was thinking. He leaned over the stone basin, frowning as though deep in thought.
Will considered it, then asked, "Could we use Transfiguration to make a second stomach, then drink it?"
Dumbledore paused, then smiled. "That's an interesting idea, Will, but a potion like this affects the entire body on a mystical level, not just the stomach. It acts directly on your mind, no matter how many stomachs you drink it with.
"Of course, that only applies to some potions. Others could be kept separate that way."
Will nodded. He hadn't held out much hope anyway—but now he wanted to know how to brew it more than ever.
"Then what should we do?" Harry scratched his head. "We can't exactly make the Inferi drink it, can we?"
"Perhaps we could find some Fantastic Beasts to drink it," Will said.
He remembered that Kreacher had drunk it. If a House-elf could, perhaps other Fantastic Beasts could too.
