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.

Attack formula against PT Imps
The Attack formula against PT Imps:^[1]^[2] Jet Assault & Airstrike [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }[/math] Shelling [math]\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }[/math] Opening & Closing Torpedo Salvos [math]\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 }[/math] Night Battle Night Battle data are unclear yet. With [math]\displaystyle{ \text{Atk}_\text{post-cap} }[/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]

[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} = }[/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 Formation.^[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/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].

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

All other equipment		1		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.
