# Template:Anti-PT Imp Setups

Anti-PT boat
Unlike most standard Abyssals, "PT boats" ( & ) are "very small and fast".
• All ship types suffer a severe accuracy and firepower penalty against PT boats.
• Attacking them with larger guns is not very effective, smaller guns being recommended instead.
• Support Expeditions are not affect by any of the following[1].
Attack formula against PT boats
The Attack formula against PT boats:[2][3]
Jet Assault & Airstrike
• $\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }$

LBAS[4]
• $\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.4 ; 0.7] }$

Shelling
• $\displaystyle{ \text{Damage}_\text{PT}= ( 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 ) \times \prod^{All Equipment}{\text{Mod}_\text{EquipmentAtk}} }$

Opening & Closing Torpedo Salvos
• $\displaystyle{ \text{Damage}_\text{PT}= 0.3 \times \text{Atk}_\text{post-cap} + \sqrt{\text{Atk}_\text{post-cap}} + 10 }$

Night Battle
• Night Battle data are unclear yet.

With
• $\displaystyle{ \text{Atk}_\text{post-cap} }$ the post cap attack power defined here,
• $\displaystyle{ \text{Mod}_\text{EquipmentAtk} }$ the bonuses given by equipment, described below.
Accuracy formula against PT boats
The Accuracy formula against PT boats:[5][6][7][8]
 $\displaystyle{ \text{Hit Rate}_\text{vs.PT} \text{%} = \Big\lfloor ( 0.3 \times \text{Accuracy}_\text{Atk} + \sqrt{\text{Accuracy}_\text{Atk}} + 15 ) \times 1.2 \times \text{Mod}_\text{Ship} \times \Big( \prod^{All Equipment}{\text{Mod}_\text{EquipmentAcc}} \Big) \times \text{Mod}_\text{Night} \Big\rfloor - \text{EVA}_\text{PT} + 1 }$
With
• $\displaystyle{ \text{Acc}_\text{Atk} }$ the standard accuracy described here
• PT boats are "DDs" in the game, so the $\displaystyle{ \text{Mod}_\text{formation} }$ 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 $\displaystyle{ \text{Mod}_\text{PT} }$ modifier.
• $\displaystyle{ \text{EVA}_\text{PT} }$ the PT estimated evasion described bellow,

The main Accuracy modifiers are
• $\displaystyle{ \text{Mod}_\text{Amagiri} }$ being include in $\displaystyle{ \text{Acc}_\text{Atk} }$:
• 65 for
• 35? for DD and DE adjacent to Amagiri Kai Ni/D.
• 0 otherwise.
• $\displaystyle{ \text{Mod}_\text{Ship} }$ the bonus given by ship types, described below,
• $\displaystyle{ \text{Mod}_\text{EquipmentAcc} }$ the bonuses given by equipment, described below,
• $\displaystyle{ \text{Mod}_\text{Night} }$ being 0.7 during night battle, 1 during day battle.

has the ability to prioritize focusing on attacking PT imps with significantly increased accuracy if any are present.

• DD placed in the composition slots above and below her will gain a noticeable accuracy boost and will prioritize attacking PT boats if any are present.
• The PT boat targeting rate is 100% for all affected ships [9].

During Events, some special bonuses may be added, with "historical" ships and equipment gaining some accuracy bonuses[10].

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:
