Ah, one of us might be confused. I think this was before her final attack? Just because Obito's body was already torn to shreds, she was getting another attack ready that resembled a chakram.

I dont know what she's trying to do bcus that Paper Person of God Technique I think was her strongest attack ever exist. If that was her final attack and stronger than the previous attack, why she didnt used it earlier?
She takes time making a preparation just to set up that trick attack bcus she knew that Obito can go intangible, so???
I think this final attack still revolve around explosion, just it bigger than this,

Or she just preparing the next attack just for the sake to fight Obito until her last breath, meaning that tech has no significance.
