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].
Yamato-class 2-Ship Special Attack
If triggered:
- The flagship will do a 1st & 2nd attack,
- The Helper will do a 3rd attack,
- Each attack targets a ship at random,
- If all enemies sunk, then touch stops early.
- 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]

- 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{Luck}_\text{FS} }[/math] the flagship's
Luck,
- [math]\displaystyle{ \text{Luck}_\text{2nd} }[/math] the 2nd ship's
Luck,
- [math]\displaystyle{ \text{A} }[/math] being 2 if Yamato is flagship, 0 otherwise,
- [math]\displaystyle{ \text{B} }[/math] being 5 if Musashi is the helper, 0 otherwise,
- [math]\displaystyle{ \text{C} }[/math] the bonus for equipping a
Surface Surface Radars (5+ LoS?)[3], being:
- 10 if 1 ships has a radar,
- 20 if both ships have a radar,
- 0 otherwise.
Yamato 3-Ship Special Attack
If triggered:
- Yamato will do a 1st attack,
- The 2nd ship will do a 2nd attack,
- The 3rd ship will do a 3rd attack,
- Each attack targets a ship at random,
- If all enemies sunk, then touch stops early.
- 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.
Currently measured above 70%, it seems similar to Big 7 touches:
- Trigger rate is affected by:
- The Level and luck
stat of the participating ships.
Surface Radars (5+ LoS?) on attacking ships (+8~10%)[1].
- Can be triggered even if artillery spotting fails to activate.
- Can only be activated once per sortie.
- Has a chance to trigger every time Yamato 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.
