*Easy grinding setup : 2CA, 1CAV, 1DD, 2CLT (or 1CLT+1BB/CVL). Must bring total 3 [[Drum Canister|drums]] on 2 ships (e.g. 2 on DD, 1 on CAV) and a seaplane with AA to gain air superiority. There will be '''no LOS requirement for A C E G H route''' and only two battle on your way to boss - best of all, you won't encounter any enemy carrier at all and gain some steel in node G for your repairs.

**1 CL(Flag) 4 DD and 1 BBV loaded with seaplane bombers and/or [[Ka-type_Observation_Autogyro|Ka-type Observation Autogyro]]. This composition gives maximum ASW for killing the boss, but lower survival rate at the preboss node compared to the above compositions.
