__NOTOC__

This page is for "Effective Line of Sight" (ELoS), also called "Fleet LoS", as it pertains to branching requirements. Certain maps require the fleet to hit a certain LoS threshold in order to get routed to the boss or pre-boss. As a rule '''LoS from equipment is more important than ship LoS''' when determining ELoS.
−
Currently, there are three known purposes for Line of Sight (LoS):
 
−
* Increasing success rate in the detection phase, which allows participation in aerial combat.
 
−
* A higher '''Fleet total LoS''' (FLoS) [[Artillery_Spotting#Trigger_Chance|positively correlates]] with the trigger chance of [[Combat#Combat_Equipment_Setups|artillery spotting]] for a ship's double/cut-in attack in day battle. Fleet total LoS is simply the summation of all LoS stats from your ships, including bonus from the equipment.
 
−
* '''Effective LoS '''(ELoS), which allows the fleet to reach a specific node (usually a pre-boss or boss node) instead of being diverted to a dead end. Effective LoS is employed in special maps, such as [[Events|event maps]] and extra operations maps ([[World 2#2-5|2-5]], [[World_3#3-5|3-5]]).
 
−
* There are special formula being used to calculate ELoS. As a general consensus, LoS bonus from equipment (esp. recon planes) are more important than individual ship's LoS stats.

===Formula 33===

For details on the LoS {{LOS}} stat, please see [[Stats#Line of Sight|Stats]].
−
Similar to the New Fall Simplified formula, but reportedly more accurate. Using this model, a value of 31 eLoS would guarantee failing the 2-5 LoS check, while a value of 33 eLoS would succeed 100% of the time. It is described as follows<ref>http://ja.kancolle.wikia.com/wiki/%E3%83%9E%E3%83%83%E3%83%97%E7%B4%A2%E6%95%B5</ref>:

==Equipment LoS Weighting Modifier==
−
*Also known as node factor
+
The node factor <math>C_{n}</math> affects the weighting of equipment LoS.
−
*In some maps, weighting of equipment would be higher than that others.
+
* It depends on the map (''see the [[#Estimated LoS|below]]'').
−
*It is represented as C<sub>n</sub> in the formula.
+
The equipment and improvement multiplier <math>C_{e}</math> and <math>C_{\star}</math> will affect the "real" LoS given per equipment.
−
*For all tested nodes, C<sub>n</sub> for 2-5 is 1, for 3-5 and 6-1 are 4, for 6-2 and 6-3 are 3.
+
* It depends on the equipment type (''see the [[#Equipment Types|below]]'').
−
**That mean equipment LoS are 3 times more important in 6-2 and 6-3 compare to 2-5 and four time as important in 3-5 and 6-1.
 
−
**In other words, ship LoS are less effective in those maps with higher equipment weighting modifier.
 
−
*In 2-5, F33(C<sub>n</sub>=1) have to be larger than 31 to have a chance to enter boss and 33 to guarantee boss entry.
 
−
*In 6-2, F33(C<sub>n</sub>=3) have to be less than 43 to guarantee F>H and more than 40 to guarantee H>K
 
  
 +
Because of those factors:
 +
*Some equipment are more efficient to provide LoS,
 +
*Ship LoS is less relevant, notably in maps with higher node factors.

During the Summer 2014 event, there were many player reports where players of similar HQ levels have differing effective LoS requirements, leading to confusion among many players. This hinted to a ''possibility'' that effective LoS scales to level. Do not be surprised if you level up or reach the next HQ bracket (e.g. HQ lvl 60-99, 100+) and fail to reach boss node when you did reach the node the previous sortie.

It is not recommended to stack carrier-based recons or seaplane bombers because too many can compromise the combat ability of your fleet.

Another way is to level your ships. Because LoS increases as you level, marrying your ships means their LoS stat can go even higher.

This page is for "Effective Line of Sight" (ELoS), also called "Fleet LoS", as it pertains to branching requirements. Certain maps require the fleet to hit a certain LoS threshold in order to get routed to the boss or pre-boss. As a rule LoS from equipment is more important than ship LoS when determining ELoS.

For details on the LoS Line of Sight stat, please see Stats.

Calculating LoS

Formula 33

Formula 33, sometimes referred to as F33 is the most accurate "Fleet LoS" calculation formula known. It is described as follows[1]:

LoS Formula 33
[math]\displaystyle{ \text{LoS}_\text{Fleet} = \sum_{\text{All Ships} } \sqrt{LoS_\text{Ship} } + C_{n} \times \sum_{\text{All Equipment} } C_{e} \times ( \text{LoS}_{e} + C_{\star} \times \sqrt{\bigstar} ) - \lceil Q \times Lv_\text{HQ} \rceil + 2M }[/math]
With
  • [math]\displaystyle{ \text{LoS}_\text{Ship} }[/math] the ship's base LoS Line of Sight.
    • Total LoS Line of Sight of Visible Fit Bonuses should be added to this part, unlike equipment improvement bonuses.
  • [math]\displaystyle{ C_{n} }[/math] the Node factor, it represents the weighting of the formula that is known to vary across different maps and nodes (see below),
  • [math]\displaystyle{ C_{e} }[/math] the equipment multiplier (see below),
  • [math]\displaystyle{ LoS_{e} }[/math] the equipment's base LoS Line of Sight, excluding visible fit bonus,
  • [math]\displaystyle{ C_{\star} }[/math] is the improvement modifier of the equipment (see below),
  • [math]\displaystyle{ \bigstar }[/math] the equipment's improvement Improved level,
  • [math]\displaystyle{ Q }[/math] the HQ level modifier, varying depending on the map:
    • 0.35 on 5-2 and 6-3.
    • 0.4 otherwise.
  • [math]\displaystyle{ Lv_\text{HQ} }[/math] the HQ level.
  • [math]\displaystyle{ M }[/math] the number of empty ship slots in the fleet:
    • 0 for 6 ships fleet,
    • +1 increase per missing ship,
      • This value can increase mid-sortie if a ship is sunk or evacuated.
    • -1 for a full Striking Force Fleet (7 ships).
Notes
  • Equipment LoS weight more than ship LoS.

Equipment LoS Weighting Modifier

The node factor [math]\displaystyle{ C_{n} }[/math] affects the weighting of equipment LoS.

  • It depends on the map (see the below).

The equipment and improvement multiplier [math]\displaystyle{ C_{e} }[/math] and [math]\displaystyle{ C_{\star} }[/math] will affect the "real" LoS given per equipment.

  • It depends on the equipment type (see the below).

Because of those factors:

  • Some equipment are more efficient to provide LoS,
  • Ship LoS is less relevant, notably in maps with higher node factors.

Estimated LoS

Data sourced from TsunDB. Values are the lowest and highest reported LoS for routing. Please note that there may be some margin of error due to random routing.

Events

In events, LoS cheks are also performed following the same rules, but will additionally vary with difficulties, higher difficulties recruiting higher LoS.

LBAS LoS

Unlike ship mechanics, LBAS do not need/utilize the LoS stat and so this stat is mostly useless.

The only use for LoS is for "Defense Fighter-Power" in air defense mode, where it determines the "Reconnaissance Defense Bonus" ([math]\displaystyle{ \text{Mod}_\text{recon} }[/math]) for Reconnaissance SeaplaneRecon Seaplane Recons, Large Flying Boat Large Flying Boats, Reconnaissance Aircraft Carrier Recons, and Land-based Reconnaissance AircraftLB Land-based Recons:

≥9 1.16 1.3 1.24
8 1.13 - 1.18
≤7 1.1 1.2 -

The LoS on all other aircraft or in other LBAS modes is not counted.

FAQ

Q: Why do I keep getting offrouted?

A: Double check that your fleet LoS according to relevant formula meets the LoS threshold for the map. Viewers such as KanColle Command Center Kai, Poi Viewer, KCANotify, KanColle Viewer and Electronic Observer can calculate your fleet's LoS easily for you.


Q: How do I increase my LoS?

A: Reconnaissance seaplanes are the fastest way to raise LoS. The other easy way is to stack radars. Upgrades to reconnaissance seaplanes are also a good way to increase LoS when slots are limited. It is not recommended to stack carrier-based recons or seaplane bombers because too many can compromise the combat ability of your fleet. Another way is to level your ships. Because LoS increases as you level, marrying your ships means their LoS stat can go even higher.


Q: I had enough LoS, how did I get off routed?

A: Planes that are wiped out no longer contribute to LoS. If you were depending on bombers to hit the LoS threshold, you can fall under the threshold when encountering heavy enemy anti-air.
