Damien's instincts.
They had accompanied him since his days in the First Dungeon, constantly improving and aiding him in his path to power.
As he got stronger, he stopped relying on them. He didn't need instinctive reactions when his intentional actions were enough to solve any problem.
However, his instincts still appeared every once in a while.
And every time they appeared, they led him to something amazing.
Sometimes it was in the form of another person, sometimes it was an opportunity he never would've seen coming, and sometimes, it was a guiding hand that helped him manifest his power in the most effective way.
Damien's instincts never had time to help him in the last aspect because he wasn't fighting people who couldn't truly harm him.
The current battle was different.
Perhaps it couldn't kill him, but the homunculus was truly a God. Damien had no way of confirming that it truly didn't have any means to send him to hell.
