Gravity, PP, machines, animal summons, king of hell, purple mind rip. These arent rinnegan abilities. Hence why no other rinnegan users have shown this ability. These are nagato's jutsu and they dont require rinnegan to use. For ex, gravity push contains all seishitsu and requires the manipulation of all of them to use. So people who have mastered all of the seishitsu can use it. The other jutsus properties are unknown, but my guess is asura path is yin release, giving shape and form to things, Animal path is yang release, giving life to mythical creatures + water release and explosion kekkei genkai ( The foam and bombs of the animals), Naraka path is yin-yang release, giving form and life to the form, Preta is yang release, it is the user's own chakra inversely positioned and given life but when faced against natural energy, something which has been shown to give life to inanimate objects, it gets overloaded because it is fed with the same material it is made of?
