An interesting question.
How could they give a Boggart, which had no attributes to begin with, attributes that would make it take on a particular form?
Albus's theory of Transfiguration gave Anton an idea: the state of transformation between "nothing" and "something." In this state, things existed in an infinite superposition, yet seemed close to "nothing."
But it was not, after all, "nothing." It was unaffected by time, unguided by Fate, and untouched by the human heart.
It was more like a kind of formless chaos—and it needed to be given absolute intent, or Transfiguration would spiral out of control. That was Dumbledore's answer.
Intent was like a signpost that made chaos collapse into something real, guiding it to take shape and appear in the real world as a tangible result.
But Anton didn't want a specific object. He needed an intermediate state he could use for experiments.
In other words, he wanted to guide the Boggart from "nothing" toward the brink of "something"—to the moment just before the formless chaos began to collapse into shape.
That was where the cleverness lay.
Boggarts were Dark Magic Creatures that sensed the human mind through the emotion of fear. The mind they reflected gave them the intent to transform.
The answer was obvious.
"Twisted Cage!"
Anton pointed his Wand at himself, gripping it in reverse. Its light sank into his chest, gradually adjusting the state of his inner self.
Then he looked over at the House-elf, Dobby. Dobby was standing guard in front of a box. Seeing Anton look his way, it hurriedly opened the box in its hands.
It closed its eyes in fear, not daring to look at the oak box, which was only the size of a Muggle shoebox. Boggarts were such terrifying Dark Magic Creatures. It didn't want
