I've tried to list all "most profitable" combinations for Chapter 1+Megail's route.

They all share the same base: Chapter 1: Yhilin Bank + Mine Processing + Stineford Magic Shop Megail's route: Embassy + Ardoheim Magic Trade + Aramite Supplier + Desert Bounty Office + Eustrin Manufacturer

I've played around, and didn't find a reason to turn my back on those excellent investments (well, the Aram Supplier isn't that good, but it's cheap and I didn't encounter a combination where skipping it helped in any way).

In all cases, we do Aka's route before Megail's, just to make sure Yhilin Score >= 6. The war should always be winnable with 0 Chaos, 0 Collateral and Essence Shielding first (with conservative choices, and the army taking the blunt of the damages instead of the city), especially as we can always get Megail to 100 in time (by choosing her first during the Reunion; one may also need to buy the Yhilin Bank for her if they refused to invest in her special project).

Yhilin supplier is bought in Megail's route if there's money left, and later if not (not permanently missable). Yhilin Public Works I is bought if we have exactly 5,000 extra ProN during Chapter 1.
