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.

=Introduction=
This page is for Effective Line of Sight (ELoS) as it pertains to branching requirements. Certain maps require your 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 a details on the LoS {{LOS}} stat, please see [[Stats#Line of Sight|Stats]].

===Formula 33===
===Formula 33===
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
* Also known as node factor.
*In some maps, weighting of equipment would be higher than that others.
* Depending on the map, equipment is weighted with more importance.
*It is represented as C<sub>n</sub> in the formula.
* It is denoted as C<sub>n</sub> in the formula.
*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.
* 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.
**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.
** This means equipment LoS is 3 times more important in 6-2 and 6-3 compared to 2-5 and 4 times as important in 3-5 and 6-1.
**In other words, ship LoS are less effective in those maps with higher equipment weighting modifier.
** Ship LoS is less effective in those maps with higher equipment weight modifiers.
*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 2-5, F33(C<sub>n</sub>=1) have to be 31< to have a chance to enter boss and 33≤ to guarantee branching to the boss.
*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
*In 6-2, F33(C<sub>n</sub>=3) have to be 43> to guarantee F>H and 40< to guarantee H>K.
=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.
