Is it? Even if his ocular power is weakened, his left eye still produces the Six Paths Chakra. And I don't think the Rinnegan jutsu necessarily have a high cost for each use (like Tsukuyomi, Amaterasu).

I seriously doubt his Rinnegan could jump into S/T at that point, and who knows what other abilities he could or could not use. His Rinne powers were certainly weakened.

Regardless, I hear what you're saying — honestly, but I have too little information to work with. Just don't know what to make of it. ¯\_(ツ)_/¯

But an ultra-high level jutsu like Amenotejikara which he can only cast a few times, is still available.

I believe that is a misconception. He used Amenotejikara three times successfully in chapter 674, with the fourth one failing because Madara moved outside his range.

Chapter: 674

Later on, we learned that he made a number of unsuccessful attempts to exit Kaguya's sand world, followed by only two uses of Amenotejikara.

Vs Kaguya

Basically, his entire left was unusable at that time — similar to what happened at V.O.T.E., just not as severe.
