Baldur's Gate 3 has an average completion time of 75-100 hours. If you want to complete every side quest, that number will easily reach 200 hours. That means even Act One is going to take a while.

Well, we've been wandering around for hours, so you can say with certainty what needs to happen before we move on to Act Two in BG3.

If you've already completed the introductory Nautiloid mission, feel free to skip to the next chapter, as you obviously can't return to it without starting a new character. There's not much to do on the Nautiloid, but there is one thing that is huge.

This is definitely the best weapon you can find during Act One (including Adamantine weapons. Yes, I think it's better). The Everburn Blade is a large sword that deals extra fire damage on hit.
