AFAIK the optimal way to clear E4 Hard is to sparkle/double expeditions 2FBB/2DD/1CA/1CVL for north (since having a CV will throw you to I) to chip on the boss HP, then change to either a combination of BB/CA(V) (BB can't be more than 4) or 3BB/1CA/1CV/1CVL for the last kill. BB+CV>4 will divert you to deadend K.

Gave up halfway through and just bulldoze the boss through the yasen nodes in medium difficulty <_<.
