you know you can read the novel right.

here a quotes of Ophis from volume 11 that'll answer both your questions.

“I - 've become weak. Right now I - am twice as strong as the Two-Heavenly Dragons at their strongest times.” ... “Samael took my power, I released my power in the form of snakes in another space. That, is what I just went to retrieve. So I'm only twice as strong as Two-Heavenly Dragons.”
