Can I do both underdark and mountain pass?

[Mr.Zombie]

In terms of quests can I complete both mountain pass main quests and grymforge main quest or I'm forced to choose?

I know at a certain point one area get auto completed, but I don't understand if it's me not being fast enough or something.

Yes.

You're only locked out of the Mountain Pass and Act 1 areas (including the Underdark) once you progress past a certain point of no return warning message at the end of a big dungeon in Act 2.

You don't even need to double back either, as you can access the Mountain Pass from the Act 2 location and likewise you can access the Underdark from the Act 2 location as well.

dont go mountain pass before doing the refugee missions if you return from just entering and thne going back everyones dead.

Is there a point of no return?

Don't step on the boat OR don't go up the elevator. I'd count the boat as starting a timed mission and the elevator as Act 2

think its the tavern atleast what i heard i spent 180 hours at this game so far and havent passed the shadows areas lol

So if I want to do both quest lines I have to basically do the grymforge quest, then I can go do the mountain pass and then I can do every secondary quest?

(by grymforge quest i mean saving nere and the gnomes)

underdark and grymforge is still considered act 1 and will not scuff any quests, mountain pass is considered act 1.5 and will scuff some quests as it's used as a "time skip"

grymforge does have a time sensitive quest but it doesn't scuff any of your act 1 quests like the mountain pass.

The zone with Nere is separate from the "underdark." So as long as you don't go there nothing should progress without you. I did the mountain pass after doing all of the underdark and grymforge areas though. I forget it's there.
Best advice is to stop worrying about what you'll "miss," that's what a second play through is for.
My first play through I did something before something else and lost the chance to go do that other thing. That's what happened and I kept on going. You can't save everyone.

The point of no return is very obvious in Act 2. It has to do with the thing they're all looking for. And you get a pop up I think before even entering the area to start it. It says something about the consequences of your actions will have an impact and could cut you off from certain parts of the story if you haven't completed them yet.
