In my playthrough, I definitely had a hard time between choosing one of the two Routes ;w;, even with all the calculations I did to find out if I can balance out both Nauxus and Axel's trust points in me. But alas, there can only be one to choose from despite entering the Neutral/Good Ending of the first story arc of the game (You can still access both tribes through this ending at least). As for my choice, I went with the Neutral/Good Ending with Nauxus and Thane staying at the tavern!. With the trigger of the Selye Fight and also defeating him with the usual bind up, defend, holy fist strat and whatnot [After 2 days in completing “The bathhouse opens for business” and “The war ends - the war (part 5)”], I was able to get the Star Emblem from Nauxus (Either get it from him at the Lizard Tribe Village Office or when he visits you at side of the Tavern). Unless you chose the Neutral/Good Ending with Axel's Favor, you won't be able to get it from him because of the Suspicion Points +3 you made in the entirety of the story by choosing Axel over him owo.
Also with the Stat Wise matter, I did also increase my Charisma by a lot and the rest of the stats being balanced enough (Though I mostly had Int, End, Str, and Agi in this order from what I remember which still got me through the entire game Nyeah! OwO). I'm sure as the story progresses with more quests, enemies, bosses, and with new areas to explore you'll make a great adventurer wolf boi! UwU. Just gotta be patient with Caro's work pace and let him take his time~!.
Soo for my opinion, it would be Nauxus' route! (If you prefer a heartfelt ending and easily obtaining the Star Emblem from him in the Selye Fight Aftermath). Axel's feelings on the MC still doesn't change regardless with having his favor in the Neutral/Good Ending 0w0; You could still try the Neutral/Good Ending with Axel on a different save file in your spare time if you'd like!
I also just referred to Redyoshi's Guide for the game and it really helped me a lot with my choices and I'm pleased with what I have so far after a couple of hours of thinking it over! (Here's the link to it btw 0w0>https://docs.google.com/document/d/1HjgBoSAq4659ANHfDyhqaSqqgL9fdVHKBp3hZ2-auUE/.... Soo nyaa! This is all I have to share!
Take care and have fun<3! UwU
