@Ninja. That was 3TS Genjutsu that Itachi was using, @ what you said with Sasuke and Kakashi, referring to Sasuke mostly. He used 3TS Genjutsu on Bee to, but in that case, attacked simultaneously.

The thing with Itachi as well. His 3TS Genjutsu is still almost (Almost I say), Tsukuyomi level. Consider vs Deidara and Orochimaru. There's also this feat for him from the novel. In the chunin exam final round. He made this kid named Nemui experience himself dying, over and over again (Speaking accurately, every time the kid saw his Sharingan). The whole thing is a lot to dive into, so i'll just say that.

I can't attach pictures so, if you care enough, scroll to the point where Sasuke broke Tsukuyomi ^, and view what Zetsu said. This is toward your skepticism, of whether Itachi would be able to do anything while performing Tsukuyomi.

Even though he may have said that (Zetsu), he might still be wrong so.. 3TS Genjutsu go!

I think if Itachi uses basic illusions with his MS, he may be able to attack simultaneously, like vs Bee.
