Mechanics
Anti-PT boat
|
Unlike most standard Abyssals, "PT boats" (PT Imp Pack & Schnellboot Imp Pack ) 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
- [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.5 ; 0.8] }[/math]
- LBAS[4]
- [math]\displaystyle{ \text{Damage}_\text{PT}= \text{Atk}_\text{post-cap} \times \text{Rand} [0.4 ; 0.7] }[/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 boats
|
The Accuracy formula against PT boats:[5][6][7][8]
[math]\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 }[/math]
|
- With
- [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math] the standard accuracy described here
- PT boats 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,
- The main Accuracy modifiers are
- [math]\displaystyle{ \text{Mod}_\text{Amagiri} }[/math] being include in [math]\displaystyle{ \text{Acc}_\text{Atk} }[/math]:
- [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,
- [math]\displaystyle{ \text{Mod}_\text{Night} }[/math] 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.
- The

bonus does not stack with the Armed Boats![Soukoutei (Armored Boat Class)](https://yksk.kancollewiki.net/w/images/thumb/8/81/Equipment_Card_Soukoutei_%28Armored_Boat_Class%29.png/160px-Equipment_Card_Soukoutei_%28Armored_Boat_Class%29.png)
ones.
- Using other setups improving accuracy is also advisable:
