Anti-

Unlike most standard Abyssals, are very small and fast.

All ship types suffer a severe accuracy and firepower penalty against PT-Imp.
Attacking them with larger guns is not very effective, smaller guns being recommended instead.

Accuracy formula against PT-Imps

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

[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 \text{Mod}_\text{Equipment} \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }[/math]

[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 described bellow,

PT-Imp stats
Type	Luck	Eva	[math]\displaystyle{ \text{EVA}_\text{PT} }[/math]
Type	Luck	Eva	Line Ahead	Echelon	Line Abreast
PT Imp Pack	?	?	81?	87?	?
PT Imp Pack II	60	220	80	87	85
PT Imp Pack III	60	250	82	89	88
PT Imp Pack IV	?	?	?	84?	?

[math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being:
- 64 for Amagiri Kai Ni/D
- 32 for DD and DE adjacent to Amagiri Kai Ni/D.
- 0 otherwise.

[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} = 0.42 }[/math],
[math]\displaystyle{ \text{Mod}_\text{Add} = 24 }[/math],

[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 Formation.^[5]

[math]\displaystyle{ \text{Mod}_\text{Ship} }[/math] the bonus given by ship types, described below,
[math]\displaystyle{ \text{Mod}_\text{Equipment} }[/math] the bonuses given by equipment, described below,
- When several equipment are used on a ship, it is then the product of those bonuses.

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.

Ship Type	[math]\displaystyle{ \text{Mod}_\text{Ship} }[/math]
DD & DE	1.0
CL, CLT, & CT	0.82
All other types	0.7

Equipment		[math]\displaystyle{ \text{Mod}_\text{Equipment} }[/math]
Equipment		1st equipped	2nd equipped
	Small Guns & Main High-Angle Guns^[6]	1.3	1.15
	Secondary Guns & Secondary High-Angle Guns	1.55	1
	AA Guns	1.45	1.35
	Skilled Lookouts	1.75	1
Armed	Armed Boats	1.45	1.3
	Seaplane Bombers & Seaplane Fighters	1.5	1
	Dive Bombers & Jets	1.375	1.2
All other equipment		1

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:
- Hidden accuracy bonus setups,
- Sparkled ships.

For the most part, underestimations (up to 10% difference in hit rate) are observed. It is not clear what may lead to this at the moment. ↑ Medium Main High-Angle Gun may work too.
