Good feedback. I definitely agree with you that it feels like you need to do every sidequest in the prison. That makes them less "sidequests" and more "mandatory main quests". I am pretty early on though, so I haven't tried much else.
I am not entirely ready to say it's like that for sure, as I am only level 2 and am still trying some things.
Dialogue options to tell Stingtail Griff has been killed, and to also return the drudane to him. Dialogue option to get Butter to join you during the fight with Griff if someone in the party has romanced her.
Correct me if I'm wrong, but isn't the entirely of the Butter "romance" about three lines long? Truly, a love for the ages, that is.
