E2: Easy or Medium (since you want to farm for Unryuu)

Use surface task force,  BB+CV < 2 in main fleet to avoid node with 3 ru battleships.

E3: Medium (Isokaze medium+ drop, gives the BB radar as reward)

Use 2CV + 2CVL for easier route, use your weak ships here so you can use your strong ships in E3 medium and E6 medium

E4: Easy (rewards are not worth it imo)

You need a pair of Kongou-class for branching, fleet compo choose 2FBB (Kongou + Haruna or Kirishima + Hiei due to specific branching), 2DD, CA(V), CVL. Sortie the ships you want to use in E4 to E3 first so you can use them later in E6 medium.

E5: Easy/Hard (U-511 drops here, but only in hard mode)

Fleet compo Akitsushima + 2FBB + CLT +DD + CV, or CAV + 2FBB + 2DD + CV. You can replace 2FBB with 2BBV but FBB + BBV is not allowed. If you do E5 on easy, s ortie the ships you want to use in E5 to E3 first so you can use them later in E6 medium.

E6: Medium (medium for shoukaku and zuikaku remodel item)

Use carrier task force. Any comp without CLT is okay (CLT goes to dead end).

E7: Easy

Use carrier task force for fastest route to boss (high chance to start at node E). Note that defeating nodes X,Y,K reduces boss armour. CLT goes to dead end.
