This war is a pain to optimize correctly since we don't have the entire war laid out yet. Looking at the text, sending ground troops to New Givini is a bad idea, while if you kill Fuzkao ASAP at the beginning of the war and go fleet route, you miss out a bunch of LoB Damage to negotiate with LoB. IIRC if you send Sabitha to Fuzkao at the first choice, "Sabitha Acted" also switched to ON. Can someone reconfirm it?
Edit: If you go fleet route, you aren't given the option to negotiate with LoB, it's available only on the LoB route for me.
