Talked with Vetex for two seconds in patreon chat and he did reveal some of the side quests that the MC canonically completed. I do want to note this isn’t a list of every single one so it’s still possible they canonically did other ones like the Maya quest and what not.
He also confirmed that all side bosses in the bronze sea will likely be added. My question to him was also asking if Juraserva was gonna be added in full release which he’s confirming here as well.
This does mean that undead Octavious with whatever experimental curse is probably gonna be like mid-nimbus MC level. I guess being braindead really hinders someone’s ability to fight, who woulda thunk it?
