Yata Mirror

The Yata Mirror was equipped to Itachi's Susanoo, in its left hand and, is considered one of the three sacred treasures. It is said to be endowed with all nature transformations and as such changes its own characteristics depending on those of the attack it receives, making the technique ineffective. Zetsu claimed that this, combined with the Sword of Totsuka held in its right hand, essentially made Itachi's Susanoo invincible.
