"Avada Kedavra!"
An eerie green light sliced through the darkness like the Grim Reaper's scythe.
The light faded.
"Aaargh!"
Dormammu let out an agonized scream that shook the entire Dark Dimension.
His enormous face, formed from energy, twisted and contorted as though he were suffering unbearable pain.
"What magic is this?!"
Dormammu's voice held a trace of fear and disbelief.
He felt that the green light had torn away a portion of his soul.
It had not been wounded, but utterly annihilated!
He was the Lord of the Dark Dimension!
His soul was fused with the entire Dark Dimension, vast beyond measure.

This magic seemed to ignore his defenses and his sheer magnitude, acting directly on his soul.
It was like some kind of power that operated on the level of fundamental laws!
Dormammu's mind reeled.

As long as he did not give her a second chance...
"I admit I underestimated you."
Dormammu's voice was low:
"That spell is indeed powerful. If you possessed power equal to mine, that last strike would undoubtedly have killed me."
"But you are still far too weak. No spell can bridge the gap in our power."
Hermione nodded.
"I knew that wouldn't kill you, and I never intended to finish you off just like that. All I needed was to confirm that the Avada Kedavra Curse worked on
