Is there any other powers for Itachi could Sasuke?

[GrayParadise]

Talking to my friend ATM, he just got me thinking.

You know how when he bumped his tigers on his forehead he gave him power. Before he died the second time he bumped his head on him. Could that be another type of transfer of power

I always thought that cus he looked him dead in the eyes if so that jus makes itachi that much better of an god

 

[The Necromancer]

I theorize that he gave sasuke his Totsuka and Yata mirror. There were little to no feats from these spiritual weapons with 0 back story, and they would be immensely useful in this fight.

That would be a cheatcode for sasuke.
