Summoning: Triple Rashomon - an enhanced version of the base Summoning: Rashomon, which creates not one, but three Rashomon gates at once. To perform it, two summoning seals must be completed. The gates work the same way as a single Rashomon, but the defense is tripled: the first gate takes the attack upon itself, the second reduces its power, and the third disperses the pressure, causing any attack to lose strength before it even manages to reach its target. An additional plus is the absence of hand seals, which speeds up its application. (Possibly depends on the user)
This technique saved Orochimaru from the Tailed Beast Ball, which, in his words, would have killed him if he had taken the hit directly.
Also, the gates can be summoned not only in a line one after another, but also in a wide formation surrounding the opponent. On the door tiles, launch mechanisms are built in, capable of firing volleys of blades through a chain system. However, these projectiles can damage the ground at the base of the gates, weakening the foundation and causing them to collapse if fired too close. (The whole paragraph is about events in the anime)
