On last HP gauge on E4 hard mode now, basically im copying the strategy in this link, 潜艇T流
Using submarine i14 as decoy is very good, tried 7 submarine but only 50% chance in boss since cannot retreat ship
and taiha 西村 ship seems can do special bonus attack on boss, taihai can even hit boss 20 hp
砲撃支援 is a must since the route is so long so many battle
https://zh.kcwiki.org/wiki/%E6%94%BB%E7%95%....83.A8.E9.98.9F6 史実艦(西村) with 志摩 flag, 90% go in boss node, even retreat 2 ships still can hit 70-80%hp boss
hardest in E4 should be S win Z6
Thanks for sharing
i do E4 normal, yesterday fail to reach z6 after a few try, i go other nodes first...
today try z6, just got S rank and unlock the boss node
my E4 z6 fleet:
» Click to show Spoiler - click again to hide... «

last one is support expedition
LBAS all aim z6
» Click to show Spoiler - click again to hide... «

go z6 with >> , then come out some orange word and come back like this
