Anti- Setups

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.

Estimated PT-Imps' evasion terms
Type	Eva
Type	Line Ahead	Line Abreast	Echelon
PT Imp Pack	81	?	87
PT Imp Pack II	81	86	88
PT Imp Pack III	83	88	90
PT Imp Pack IV	84	?	?

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 Formation.^[5]

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

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.

Equipment Setups
Equipment layout	Bonus			Notes
Equipment layout	DD	CL	CA/BB	Notes
	50%	25%	N/A	Adding more main guns does not increase the hit rate. Adding more lookouts halves the rate.
	50%	25%	N/A
	100%?	50%	30%
	100%?	??	??	Best anti-Imp setup.
	N/A	35%	15%
	N/A	??	75%	Only applies to SPB & SPF.
	10%	N/A	N/A	Destroyer only.
	30%	N/A	N/A	Destroyer only.
	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^[9]^[10]. 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:
- Hidden accuracy bonus setups,
- Sparkled ships.
