Anti-PT-ImpPT Imp Pack Setups
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.

The Accuracy formula against PT-IMPs:[1][2][3][4]

  • [math]\displaystyle{ \text{Accuracy}_\text{vs.PT} = \biggl\lfloor \left( \left(\text{Accuracy}_\text{Standard} \times 0.42 + 24 \right) \times \text{Mod}_\text{Ship} \times \text{Mod}_\text{Gear} \times \text{Mod}_\text{Vanguard} \right) \biggr\rfloor }[/math]

With:

  • [math]\displaystyle{ \text{Accuracy}_\text{Standard} }[/math] is the standard accuracy described here
    • PT-Imps are "DDs" in the game, so the [math]\displaystyle{ \text{Mod}_\text{formation} }[/math] for vanguard is 0.88/1.32 for the top and bottom halves respectively.
    • Historical accuracy bonuses during Events is included in the Standard Accuracy Term, i.e. it is affected by the 0.42x modifier.
  • [math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] is the bonus given by ship types, described below,
  • [math]\displaystyle{ \text{Mod}_\text{Gear} }[/math] is the bonus given by equipment, described below,
    • When several equipment are used on a ship, it is then the product of those bonuses.
  • [math]\displaystyle{ \text{Mod}_\text{Vanguard} }[/math] is 1.2 when using the Vanguard FormationVanguard.png.[5]

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

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

DD CL CA/BB
Small Caliber Main Gun Lookout 50% 25% N/A Adding more main guns does not increase the hit rate. Adding more lookouts halves the rate.

Small Caliber Main Gun Lookout Anti-Aircraft Gun 100%? ?? ?? Best anti-Imp setup.
Secondary Gun Lookout N/A 35% 15%
RADARSurface Lookout 10% ?? ?? Only applies to Surface Radars.
Secondary Gun Anti-Aircraft Gun Zuiun Model Seaplane Bomber N/A ?? 45% Only applies to Zuiun Model Seaplane Bomber Zuiun variants.

Small Caliber Main Gun Anti-Aircraft Gun 10% N/A N/A Destroyer only.
Small Caliber Main Gun Small Caliber Main Gun Anti-Aircraft Gun 30% N/A N/A Destroyer only.
Small Caliber Main Gun Anti-Aircraft Gun Anti-Aircraft Gun 50% N/A N/A Destroyer only.
The values presented above are theorized to be fixed hit rates.
  • This means they are unaffected by any outside factors.
  • These rates are based on tests conducted during the Summer 2017 Event[7][8].
  • The average observed hit rate without anti-TP setups was about 40% for regular fleets and about 10% for TCF. The values on the table are the differences in hit rates compared to this.

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:
