===Map Unlocking & Progression===
'''1-6''' is unlocked after clearing [[1-5]] HP bar.
*The map will be locked at the beginning of each month, until [[1-5]] is cleared.

To clear the map, node {{MapRoute|N}} must be reached 7 times.
*Clearing this map rewards '''75 [[Ranking]] points''' and a '''[[Present Box]]'''.
*The map will reset at midnight JST at the beginning of every month.

===Stage Guide===
{{MapBranchingTable
|title = 1-6 Branching Rules
|id = 1-6
|0 -> A/empty = 
* Meet '''ALL''' of the requirements
** Amount of DD+DE ≥ 4
** Fleet doesn't contain CA(V), BBV or CVL
|0 -> C/battle = 
* Meet '''ANY''' of the requirements
** Fleet contains CA, BBV or CVL
** Amount of DD + DE in fleet is ≤ 3

|G/resource -> F/battle = 
* Fleet consists of 1 CL + 5 [DD + DE]
* 75% chance if the requirement isn't met
|G/resource -> K/battle = 
* 25% chance if the requirement to go to node F isn't met

|M/resource -> J/battle =
*Meet '''ALL''' of the following requirements:
** Fleet with at least 3 DD + DE 
** CVL + BBV + CA + CAV ≤ 2 
** Pass the LoS : '''LoS ≥ 30''' (Cn3)
|M/resource -> L/battle =
*Meet '''ANY''' of the following requirements:
** CVL + BBV + CA + CAV ≥ 3
** Fleet doesn't have 3 DD + DE
** Fail the LoS check
}}

===Tips===
There is no Boss node in this map. Instead, the final "Harbor Node" at {{MapRoute|N}} serves as the map's endpoint.
*A random amount of resources of either fuel, ammo, steel, or bauxite is rewarded upon reaching node {{MapRoute|N}}.
**The amount of resources rewarded at node {{MapRoute|N}} is great before clearing , and modest after clearing. 

'''(F)BB, CV, CLT, and SS(V) are not allowed on this map.'''
*Only BBV, CVL, CA(V), CL, CT, DD, DE, AV, LHA, AS, AO, and AR can be used.
*Using BBV, CA, or CVL will route to node {{MapRoute|C|red}} which leads to a harder route. Submarine fleets with line ahead formation appear at node {{MapRoute|I|red}} (1/2 patterns).
**This route is mostly taken if a player wishes to brute-force the map or complete specific quests.

*"Double-arrow" nodes {{MapRoute|D|pink|F|pink|L|pink}}, are ''Air Battle'' nodes. 
**Daytime combat at these nodes has two Aerial Combat phases but no shelling. It's also possible to do night battle afterward, unlike regular Air nodes.
**If the fleet has no ships that can attack during Aerial Combat, it will get a ''D rank'' (see [[Combat#Victory_Conditions|1st D rank condition]]), unless entering night combat.
*Node {{MapRoute|N}} not being considered a boss node, it will not count towards certain quests (namely {{Q|Bw1}}) that require reaching a boss node.
*Because {{MapRoute|N}} is the End Node, it is possible to advance with a ''heavily damaged'' ship (taiha) from node {{MapRoute|B|red}} or {{MapRoute|D|pink}} without risk of sinking any ship.
**An exception is if the flagship is heavily damaged, where retreat is forced. However, if it is equipped with a {{EquipmentLink|Emergency Repair Personnel|Emergency Repair Goddess|text=Damage control}}, it is possible to activate it and continue (the item is '''not consumed''' here).
*Having a ship with [[AACI]] is highly recommended to reduce damage taken on ''Air Battle'' nodes. 
*Node {{MapRoute|E|red}} is a submarine node with Echelon formation. Because this node is so minor in nature, bringing ASW equipment is not required.

===Recommended Fleet===
<tabber>
|-|Light fleet=
*'''1CL, 5DD''' 
*Route = {{MapRoute|A|blue|E|red|G|green|F|pink|B|red|N}}
**The only composition that guarantees this routing.
**You can also use '''6DD / 2CL, 4DD / 1LHA, 1CAV, 4DD / 2CAV, 4DD / 2AV, 4DD / 2AO, 4DD''' as you maybe able to get ''B rank'' at Node {{MapRoute|F|pink}} with these fleets, but these can off-route you from {{MapRoute|G|green}} to {{MapRoute|K|red}}, which is a harder route.

|-|Heavy fleet=
*'''2BBV, 1CL, 3DD''' 
*Route = {{MapRoute|C|red|H|blue|K|red|M|green|J|red|D|pink|N}}
**Should only be used for some quests such as [[Quests#Bq3|Bq3]].
**Goes through a longer and more dangerous route compared to the light fleet.
**There is an LoS check at node {{MapRoute|M|green}}. You need to have '''LoS > 30''' (Cn3) in order to go from {{MapRoute|M|green}} to {{MapRoute|J|red}}.
</tabber>

===Resource Nodes===
{{MapRoute|G|green|M|green}} are "Special Resource Nodes" rewarding respectively ammo {{Ammo}}, and fuel {{Fuel}}.

Additionally, node {{MapRoute|N}} is a special case with its unique set of rules.
*''See [[Resource Node|here]] for more details.
