The head of the Overgod suffered some pain, but it was not much. The most important repercussion is that it had become powerless.
All of its power had been sealed, the enhancement from the void universe removed, and its authority rescinded. But that is nothing compared to gaining its freedom.
This confirmed that the Supreme was dead. If the lord of Madness were alive, the repercussions would be far worse than this. It would be so bad that it would wish for death.
The Overgod smiled and said, "Don't disappoint me."
Then it left.
The god of soul shook her head as she watched him leave. "WISDOM is truly something. He is not even here, and he still defeated this old guy."
The god of Power snorted and said, "It was not a defeat. It was just a successful persuasion not to fight."
