Anti-PT ImpPT Imp Pack
Unlike most standard Abyssals, PT Imp PacksPT Imp Pack are very small and fast.
  • All ship types suffer a severe Accuracy accuracy and Firepower firepower penalty against PT Imp.
  • Attacking them with larger guns is not very effective, smaller guns being recommended instead.
Attack formula against PT Imps
The Attack formula against PT Imps:[1][2]
Jet Assault & Airstrike
  • [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Damage} \times \text{Rand} [0.5 ; 0.8] }[/math]


Shelling
  • [math]\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Damage} + \sqrt{\text{Damage}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }[/math]


Opening & Closing Torpedo Salvos
  • [math]\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Damage} + \sqrt{\text{Damage}} + 10 }[/math]


Night Battle
  • Night Battle data are unclear yet.


With
  • [math]\displaystyle{ \text{Damage} }[/math] the post cap attack power defined here,
  • [math]\displaystyle{ \text{Mod}_\text{EquipmentAtk} }[/math] the bonuses given by equipment, described below.
Accuracy formula against PT Imps
The Accuracy formula against PT Imps:[3][4][5][6]
  • [math]\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor \big\lfloor \lfloor \text{Acc}_\text{Standard} + \text{Mod}_\text{Amagiri} \rfloor \times \text{Mod}_\text{Formation} \times \text{Mod}_\text{Morale} \times \text{Mod}_\text{PT} + \text{Mod}_\text{Add} \big\rfloor \times \text{Mod}_\text{Vanguard} \times \text{Mod}_\text{Ship} \times ( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} ) \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }[/math]
With
  • [math]\displaystyle{ \text{Acc}_\text{Standard} }[/math] the standard accuracy described here
    • PT Imps are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 1.1 during shelling, and 1.2 during the torpedo phase.
    • Historical accuracy bonuses during Events are included in the Standard Accuracy Term, i.e. it is affected by the [math]\displaystyle{ \text{Mod}_\text{PT} }[/math] modifier.
  • [math]\displaystyle{ \text{EVA}_\text{PT} }[/math] the PT estimated evasion Evasion described bellow,
PT Imp stats

The main Accuracy modifiers are
  • [math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being:
  • [math]\displaystyle{ \text{Mod}_\text{Formation} }[/math] the Acc mod of each formation (see here),
  • [math]\displaystyle{ \text{Mod}_\text{Morale} }[/math] the morale effects (see here)
  • [math]\displaystyle{ \text{Mod}_\text{PT} = }[/math] 0.420.35 x 1.2
  • [math]\displaystyle{ \text{Mod}_\text{Add} = }[/math] 24(15+5) x 1.2,
  • [math]\displaystyle{ \text{Mod}_\text{Night} }[/math] being 0.7 during night battle, 1 during day battle.
  • [math]\displaystyle{ \text{Mod}_\text{Vanguard} }[/math] being 1.2 when using the Vanguard FormationVanguard.png.[7]
  • [math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] the bonus given by ship types, described below,
  • [math]\displaystyle{ \text{Mod}_\text{EquipmentAcc} }[/math] the bonuses given by equipment, described below,


Amagiri Kai Ni/DAmagiri Kai Ni
Amagiri Kai Ni D has the ability to prioritize focusing on attacking PT Imp with significantly increased accuracy if any are present.

  • Ships placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT Imp if any are present.

During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses[8].

Notes
  • It is recommended to use anti-PT setups on DDs only, such setups compromising overall combat effectiveness.
  • Having a Reinforcement Expansion is important because it can save a ship slot by containing a machine gun or skilled lookouts.
  • Combining equipment is recommended to see significant boosts to accuracy.
  • Using other setups improving accuracy is also advisable:
