Yamato gains two different special attacks on Kai Ni/Juu.

They're distinguished by how many ships participate, there's a 2-ship touch and a 3-ship touch:

Devs also have stated that the touch helpers will be updated with relevant ship implementation [1].

    • Secretary for combined fleets.
    • She must not be more than lightly damaged (小破).

    • She must not be more than lightly damaged (小破).
    • When using Musashi Kai Ni as the helper in the 2nd position with Nagato Kai Ni or Mutsu Kai Ni in the 3rd one being lightly damaged (小破) or better, there is a random chance to trigger the "3-Ship Special Attack" instead.
  • There must be 6 or more surface ships in the fleet.
    • There must be no submarine in 6-ship fleets. In 7-ship fleets, only 1 submarine is allowed.
    • There must be no surface ship in the fleet sunk or evacuated via Command Facility FCFFleet Command Facility
      Striking Force Fleet Command Facility
      during a sortie, making the remaining total < 6. Ships in the escort fleet are not counted.
  • In single fleet, EchelonEchelon.png needs to be selected.
  • In a combined fleet, Cruising Formation 4Formation 4.png needs to be selected.
  • The touch can activate even if Yamato Kai Ni Juu is equipped with ASW equipment when facing a fleet mixed with submarines.

If triggered:

  • The flagship will do a 1st & 2nd attack,
  • The Helper will do a 3rd attack,

  • The modifiers are post-cap on day battle, and pre-cap on night battle.
  • The equipment bonuses do not stack further than 1 radar and/or 1 AP shell per ship.
    • Only ships equipped with those equipment will get a bonus for their attack(s).

The attack will consume extra ammo from participating ships when triggered. The total ammo consumption will be x1.6 of the original ammo consumption of those ships when the attack is triggered.

The touch:

  • Can be triggered even if artillery spotting fails to activate.
  • Can only be activated once per sortie.
  • Has a chance to trigger every time the flagship takes a turn at shelling.
    • In single fleet, if it fails to trigger in day battle, there is a chance to trigger it in the follow-up night battle.
  • The rate is:[1][2]
[math]\displaystyle{ \text{Trigger}_\text{Rate}\text{%} = \sqrt{\text{Lv}_\text{FS}} + \sqrt{\text{Lv}_\text{2nd}} + \sqrt{\text{Luck}_\text{FS}} + \sqrt{\text{Luck}_\text{2nd}} + \text{A} + \text{B} + \text{C} + 35 }[/math]

    • 10 if 1 ships has a radar,
    • 20 if both ships have a radar,
    • 0 otherwise.

Yamato 3-Ship Special Attack

    • She must not be more than lightly damaged (小破).
  • A pair of ships from a same "Helper Pair" must be in the 2nd and 3rd positions.
    • They must not be more than lightly damaged (小破).
    • When using Musashi Kai Ni as the helper in the 2nd position with Nagato Kai Ni or Mutsu Kai Ni in the 3rd one:
      • If the 3rd ship is lightly damaged (小破) or better, there is a random chance to trigger the "2-Ship Special Attack" instead.
      • If the 3rd ship is moderately damaged (中破) or worse, the "2-Ship Special Attack" will trigger instead.
  • There must be 6 or more surface ships in the fleet.
    • There must be no submarine in 6-ship fleets. In 7-ship fleets, only 1 submarine is allowed.
    • There must be no surface ship in the fleet sunk or evacuated via Command Facility FCFFleet Command Facility

  • The modifiers are post-cap on day battle, and pre-cap on night battle.
  • The equipment bonuses do not stack further than 1 radar and/or 1 AP shell per ship.
    • Only ships equipped with those equipment will get a bonus for their attack(s).

The attack will consume extra ammo from participating ships when triggered. The total ammo consumption will be x1.8 of the original ammo consumption of those ships when the attack is triggered.

The touch:

  • Can be triggered even if artillery spotting fails to activate.
  • Can only be activated once per sortie.
  • Has a chance to trigger every time the flagship takes a turn at shelling.
    • In single fleet, if it fails to trigger in day battle, there is a chance to trigger it in the follow-up night battle.
  • The rate is probably:
[math]\displaystyle{ \text{Trigger}_\text{Rate}\text{%} = \sqrt{\text{Lv}_\text{FS}} + \sqrt{\text{Lv}_\text{2nd}} + \sqrt{\text{Lv}_\text{3rd}} + \sqrt{\text{Luck}_\text{FS}} + \sqrt{\text{Luck}_\text{2nd}} + \sqrt{\text{Luck}_\text{3rd}} + \text{X} + \text{Y} }[/math]
With
  • [math]\displaystyle{ \text{Lv}_\text{FS} }[/math] the flagship's Level,
  • [math]\displaystyle{ \text{Lv}_\text{2nd} }[/math] the 2nd ship's Level,
  • [math]\displaystyle{ \text{Lv}_\text{3rd} }[/math] the 3rd ship's Level,
  • [math]\displaystyle{ \text{Luck}_\text{FS} }[/math] the flagship's Luck Luck,
  • [math]\displaystyle{ \text{Luck}_\text{2nd} }[/math] the 2nd ship's Luck Luck,
  • [math]\displaystyle{ \text{Luck}_\text{3rd} }[/math] the 3rd ship's Luck Luck,
  • [math]\displaystyle{ \text{X} }[/math] some yet unknown bonus variables,
  • [math]\displaystyle{ \text{Y} }[/math] some yet unknown base rate.

It is notably affected by:

  • The Level and luck Luck stat of the participating ships,
  • RADAR Surface Radars (5+ LoS?) on attacking ships (+8~10 %)[1].

It is currently measured above 70 %.
