Obito: One Rinnegan - One Sharingan.

[Cogzzworth]

If someone even has the rinnegan they are able to use all the elements. So that would mean the deva path would be able to use all the elements. Problem is he has no need to use all of them.

i dont think he'd say he can use human path if he really couldnt. would be awkward.
kabuto: so you cant use human path?
obito: um..no.
kabuto: why did you JUST say-
obito: shut up, ok?
