I held off on doing "Bidding Farewell" because I wanted to meet Davrin before making any more Lucanis romance decisions. Little did I know.
"Bidding Farewell" is marked as "failed" for me in the journal because I didn't do it before "A Warden's Best Friend" and chose Minrathous. I have had no flirt options for Lucanis since, so I'm sure that "Bidding Farewell" is key to Lucanis' romance. I get that the failed quest is my fault, I don't have the quest completely missing like others do.
All of it is so convoluted and confusing. It's such a bizarre choice to force a monumental world and romance decision before even gaining all the companions and to lock in meeting a companion into a major world choice. All of that and the general romance lockout with Lucanis has frankly soured my entire first playthrough, arguably the most important one.
Also, I think it's flat-out incorrect - like literally misinformation - that this isn't a real quest or side quest and just a conversation, so it's getting muddy now on what is actually happening with Lucanis.
It's become a domino effect of sourness. I think choosing Minrathous makes a far more compelling romance with Lucanis, but even if he was still romanceable after, why would I want to romance someone who is now hardened to me and refuses to heal me? It would be different if Hardened was only temporary until you hit certain relationship levels, but I had to leave the immersion of the game to search this, and my understanding is that it's permanent.
I also blame the writing -- there are clearly implied dire political consequences if you don't save Minrathous. There aren't if you don't save Treviso. Treviso is already occupied, the stakes aren't raised. Do people die? Yes, but people will also die in Minrathous if you don't help AND it will supposedly make the world events even worse. I don't want to save Treviso just because it lets me continue to flirt with a hot guy.
Genuinely mind-boggling and infuriating.
