@James, we @ people to make it less confusing as to who is replying to who. This is done in every forum, especially if your reply isn't replying to the one directly above yours.

@UltimateMario Sage Mode is an oddity with Genjutsu imo. Idk if it would work just because to use Genjutsu, you have to manipulate your opponent's chakra. But if the victim has Sage chakra, then your average Genjutsu user couldn't manipulate it, since you need lots of training to manipulate Nature Energy.

Though this hasn't been explored at all to my knowledge, and it could be just as likely that Sage Mode Users are susceptible to Genjutsu just like anyone else.

In any case, Itachi has only once shown use of Tsukuyomi on that scale, and since it was novel only. So I personally don't count it in his list of feats. And this wiki lists it as one of the lower tiers of canon in its policy.
