**Random offrouting, low chance of reaching the boss node or killing the boss(even if there is Wo-kai comp). The only advantage is the low resource cost. If you have 6 ringed submarines with reinforced expansion(which can equip submarine radars, enable them to launch powerful night CI), and you have a lot of time to expend, and your resource really matters, you can try this comp one or two times each day, and you may clear the map on the end of the month.

**Node {{MapRoute|D|violet}} is a maelstrom node. It's recommended to bring some radars to reduce fuel losses.

**The best way to kill the Re-class and the boss is Nagato special attack. Equip [[Nagato Kai Ni]] with two of your best guns (The firepower should be as high as possible, such as [[46cm Triple Gun Mount Kai]] and [[Prototype 51cm Twin Cannon]]), one radar and one AP shell. [[Mutsu Kai Ni]] should also follow this pattern, but it's recommended to give Nagato 46 or 51cm guns to make her range VL in order to attack first. Since enemy ships have really high firepower, it's important to keep initiative.

**The best way to succeed at killing the the harder boss compositions is utilizing the Nagato-Class special attack. Equipping [[Nagato Kai Ni]] with two high firepower/Very long range guns(i.e. [[46cm Triple Gun Mount Kai]] and [[Prototype 51cm Twin Cannon]]), one radar and one AP shell is recommended. [[Mutsu Kai Ni]] should also follow this pattern, but without utilizing VL range guns to make Nagato shoot first.

**Elimininate two enemy destroyers(and possibly one Tsu-class CL) before the Nagato attack is very important to make sure that the three powerful hits are not wasted on those cannon-fodders. So it's recommended to use boss support or take other measurements. For support, accuracy is more important than firepower. It's also possible to use a 4CA2DD support to reduce resource consumption(the CA should reach 123 firepower to make sure that enemy destroyers can be killed in Head-on).

**Elimininating the enemy destroyers before the Nagato attack helps with concentrating fire on the thougher targets of the Node, so it's recommended to use boss support, opening torpedoes and/or opening airstrikes.

**Nagato+Mutsu+2CAV+2DD grants air parity on node H. One of the CAV should be [[Mogami Kai Ni Toku]] for opening torpedo attack.

**Nagato+Mutsu+1CVB+1AO+2DD(recommended): Very versatile and strong comp. The only recommended AO is [[Souya (AGB)]] which can equip armor plates to greatly improve survivability. The CVB should equip 3 jets if possible(to improve firepower to 220 cap, to get air parity on node H, and to kill enemy destroyers). The rest slot is for Saiun for preventing Red T(it's possible to kill the boss with this comp even in Head-on), and contribute to LoS.

**About LOS: For Souya jet comp, it's not difficult to fullfil the LOS requirement. For the rest comps, LOS requirement is a burden. [[Tashkent Kai]] with some radars should work well. Equiping the BB with seaplanes really does not worth it, since this significantly reduce the damage of Nagato attack.

**About Destroyers: OASW can help you on node B as well as the boss node. Tashkent can equip 2 torpedoes and 2 ASW equipments for both OASW and TCI. [[Fletcher Mk.II]] has similar function with two torpedoes and one ASW equipment. If you cannot reach air parity on node H, bringing strong AACI is recommended

**After the gauge is cleared, the boss composition will be significantly nerfed except the submarine, which is replaced by a stronger one. Stronger, 3-Item Synergy ASW would be needed to dispose of it.
