Okay, had missed the +5 from a good score at the end. Thanks.
It's frustrating that the "Bomber" Sabitha is locked behind such complex restrictions in the LoB branch. I'm not talking about stats here, just the fact that the scene is nice, and that I don't really understand the logic of making so hard to reach.
Well, guess one can just play the Airship branch if they want to read it without that much hassle.
No idea about optimization, but Esthera Island + Mestan Tower + Sabitha Fuzako is maybe the combination that feels the most right from a story point of view to me. Esthera does the heavy lifting, Mestan the tactical strikes, and Sabitha makes Incubus Kings shit their pants.
