I don't understand why he won't first reach origin realm. I know it would make the fight much easier and Felix would easily win. But I can't understand that they don't do it before the fight. There is literally no reason to wait.
Because his aim isnt the darkins. He wants to fight the unigins. The stronger he is pre-origin realm the more the bonus. If he could clutch darkins pre-origin its better than wasting his future to assure his victory
Bets on which Darkin you think will be the first to die? I want to say Manananggal but I can see it being Wendigo given how dangerous his mental/soul abilities are
