Judging by the post it seems they have info on eachother?
Deva path's effect is infinite.
Shinra tensei has the delay, bansho tennin is a bad idea as cqc is a kamui users specality, & CBT has no effect on a user inside of the kamui dimension
A good rinnegan user can lure a kamui user into attacking, and use the chakra sensing the rinnegan give to tell whether it's on or off. If it's off, then the kamui user will give off chakra and then the rinnegan user can use deva path.
I need to be clear here, is this a kamui user with both eyes? A kamui user can use attacks while in the kamui dimension, he can attack while becoming intangible. Imagine an intangible shinobi who can use katon jutsus while in another dimension. A kamui user can also warp a ninja's limbs apart from within the kamui dimension. The rinnegan has no counter for s/t & a kamui user cant be sensed while in the kamui dimension.
I'm telling you, a kamui user is invincible, a kamui user with full info on the rinnegan is tiers above them
EDIT: said the phrase "kamui user" alot
