How could Kabuto train SM?

[Masked man]

Kabuto learned SM thanks to his own or it's only thanks to Orochimaru's chakra?
I read somewhere that he had Oro's chakra to have better snake techniques and ET.
Kabuto learned SM with Oro's chakra or he could do it without it?

snake sage trained him

Kabuto went and trained under the Sage Snake. Orochimaru himself wasn't even able to use Sage Mode, I think his chakra wasn't strong enough or something.

Orochimaru got some special Chakra, like Naruto, Kushina,...

Kabutos Chakra was fodder-like.

[Descent]

Orochimaru hadn't achieved Sage Mode, yet he did have special chakra, which in fact did benefit with Kabuto's snake techniques and Edo Tensei.

i dont think he can use edo tensei anymore....
but he can still use DSM because the snake sage trained him...

[Staarkk]

Snake Sage trained him.

Kabuto is mud if he hadn't taken others abilities he wouldn't have been capable of learning sage mode he had excellent chakra control like most medical ninja but thats about it I don't recall anywhere in the manga where it said he had a large amount or a special type of chakra so he's like cell off DBZ overrated because of his stolen abilities.

I thought he used Jugo's body or something for that? IIRC didn't it say that even Orochimaru wasn't properly able to train his senjutsu?
