World 6

You can't use Support Expeditions in World 6.

Stage Guide

 * At least 3 SS are required to reach the boss.
 * There are LoS checks E -> F and F -> K. They do not have high LoS requirements (SSVs with a couple recon planes will pass), but an all-sub fleet without recon planes will be sent to H.
 * Around 25-30 ELoS (2-5 old) at HQ100 is enough but treat it as a placeholder value. Need more reports for the minimal value.
 * 1 CLT, 1 CL, 1 CV(L), and 3 SS(V) is an effective fleet for taking out the boss but it will have to go through node B where there's a Ru-class BB. Note that this fleet can send you to dead end node H.
 * All all-sub fleet will go A -> C -> D -> E -> F -> K (with sufficient LoS), however, node C is pretty harsh on subs with late-model DDs and flagship CLs.
 * Taigei in a sub fleet avoids the battle in Node C by leading the fleet to node A -> D which can be very helpful. When she is equipped with recon seaplanes, she then allows all your subs to equip torpedoes while passing the LoS check.
 * Taigei, 2DD, 3SS(V) goes A -> D -> E -> F -> K. DDs can help reduce the amount of attacks aimed at Taigei (during torpedo phase or against CAs), who have poorer armor and evasion.
 * Pattern 1 on node H has a chance to drop I-401. If you want to farm her there, 1 BB 3 CLT 1 CL 1 CV or 1 CL 3 CLT 2 CV both guarantee B -> D -> E -> H and are good enough to get S Rank.
 * To trigger Night Scout at boss node, you need either Air Incapability (28-56 FP), Air Superiority (126+ FP) or Air Supremacy. Night Scouts cannot be triggered if the day combat is done in Air Parity (with 57-125 FP when the boss battle starts)

Requires sinking the flagship at the boss node 3 times to deplete the gauge.
 * 1) Compositions:
 * 2) *B-F-H/I-K : 1BB(V), 1CV, 2DD, 2CA(V) or 1BB(V), 1CV, 2DD, 2CLT
 * 3) ** There is a LoS check for F -> I. Using either composition that fails this LoS check will to go to H instead. However, H does not contain any Flagship Kai-grade enemies, so failing this LoS check may be preferable. There is also a LoS check for H -> K. At HQ 105, 29-30.88 ELoS (2-5 fall) guarantees going H and passing the second LoS check. Starting from 31 LoS, there a small chance go to I which increases with additional ELoS until I is guaranteed.
 * 4) ***Listed values are only accurate for players between HQ 105~109. Players below HQ 105 are advised to use less ELoS than listed while players above HQ 110 will require more ELoS than listed.
 * 5) ***30 ELoS on HQ100 allows to fail the first check and pass the second one (B-F-H-K with a proper composition).
 * 6) *B-F-E-H-K: 1BB + 1CV + 1CA + 3CLTs / 2CLT, 2CA(V), 1CV, 1BB or 2CV, 2CA(V), 2CLT (29+ Refined LoS guarantees H-K)
 * 7) ** Higher chance to kill the boss, but inefficient for farming. Lower route consists of at least 1 flagship Kai ship while upper route will face one whirpool node.
 * 8) *A-D-G-K: CA(V), 2CL, 3DD (Unknown LOS check on G-K). Strongly recomended to use a CAV with at least a seaplane bomber.
 * 9) *A-B-F-I-K : 3DD, CVL, 1CA(V), 1CL

Stage Guide
NOTE: There is a chance of failing the scout mission at node H if less Seaplanes are brought. Having one or more Type 2 Large-sized Flying Boat will have a high chance of Great Success on both nodes.
 * Requires sinking the flagship at the Boss node 4 TIMES to deplete the gauge and clear the map.
 * You CANNOT bring BB(V), CA(V), CLT, CV(L), SS, or Auxiliary Ships.
 * There is a LoS check from H->J. The ELoS requirement is probably 35 ELoS (for HQ 110~120).
 * no valid tests done or found. If you want to stay on the safe side, just add more LoS than stated above.
 * Katori/Kashima can be brought to this map.
 * Node G and H are a new type of "Aviation Detection" node
 * Resources obtained in these nodes can only be received if you have obtained Rank B or higher at the Boss Node. **Otherwise, the resources obtained are nullified. The mechanism was first introduced into this map and then subsequently used in future events.
 * Node B and C are Submarine nodes with no warning. So watch out.
 * You may also opt to farm either nodes to complete Quests Bd8 and Bw5.
 * Going to Node B route is NOT RECOMMENDED as you will increase the amount of battles before reaching the Boss.
 * Chitose/Chiyoda AV may be used instead of Akitsushima (they all go through the same nodes depending on your Fleet Composition).
 * Bringing Chitose/Chiyoda AV is highly recommended due to their higher plane capacity and combat capability.
 * Akitsushima equipped with a Type 2 Large-Sized Flying Boat gains more resources than Chitose/Chiyoda AV at node G and H.
 * Battleship Ta-Class Flagship is the Flagship of node J before the 4th Final Kill
 * Destroyer Princess becomes the Flagship at the 4th Final Kill.
 * Great Success yields resource such as more often.

Compositions:

 * A-C-E-G-H-J : 1 AV + 1 CL + 4 DD (3 Battles Total)
 * Guarantees node G, letting you avoid node F which has Heavy Cruiser Ne-Class Elite. This route also lets you go through only 2 battles before the Boss Node (J).
 * Great fleet to use for consistent routing to Boss. However, your DDs may be heavily damaged during Day Battle.
 * A-C-E-F/G-H-J : 1 AV + 2 CL + 3 DD (3~4 Battles Total)
 * Sacrifices 100% routing to node G by introducing a chance to be sent to node F.
 * Higher Combat capability compared to the previous Fleet Composition due to the 2 CLs with Double Attack potential via Artillery Spotting.
 * With 1 AV + 2 CL + Katori + 2 DD, there's a chance that you could go either way. Source: Nicovideo
 * A-C-E-F-H-J : 1 AV + 3 CL + 2 DD OR 2 AV + 3 CL + 1 DD (4 Battles Total)
 * This option completely gives up the routing to node G and will go down to node F all the time which permanently increases battles to 4 total.
 * Prioritizes Firepower by using more AV or CL.

Strategy

 * Requires sinking the flagship at the Boss node 5 TIMES to deplete the gauge and clear the map.
 * Maximum 2 BB and/or 2 CV/CVL allowed to sortie.
 * The boss node has 3-5 land-based targets, Isolated Island Princess and Supply Depot Princess, accompanied by 2-3 Artillery Imps.
 * Official twitter states that Type 3 Shell isn't effective against Artillery Imps.
 * The damage mechanic for those land-based targets is still being investigated. According to WikiWiki:
 * Type 3 Shell is effective against Isolated Island Princess and Supply Depot Princess.
 * WG42 (Wurfgerät 42) is effective against all targets.
 * Daihatsu Landing Craft is effective against Isolated Island Princess and Artillery Imps (other Landing Crafts should have stronger effects).
 * AP shells are effective against Artillery Imps.
 * On the last kill boss and pre-boss nodes switches to stronger patterns as noted with ( F in the table below).

Compositions:

 * West Start: B-D-C-F-N: 1 CL (flagship) + 1 FBB (or 1 CA(V)) + 3 DD + 1 CAV (video) (5 Battles Total including Boss) or A-D-C-F-N: Akitsushima + 1 CA + 2 DD + 1 CAV + 1 BBV (5 Battles Total including Boss)
 * Node D and F are Air Raid Battle nodes.
 * Node B and C are normal battle nodes.
 * East Start: M-K-J-I-N: 2 CV CA CL 2 DD / 1 CV 1 BB 1 CL 1 CA 2 DD
 * Node I is an air defense node and doesn't eat much resources as cost.
 * To skip I (and go J-N) replace a CV with Akitsumaru Kai.
