Had an awesome plan to only do the absolute essentials in ACT 1 and then bring back Minthara to experience all the rest of the content with her, but unfortunately she is known to refuse going back to previous acts...

Or is she... ( ?° ?? ?°)

I present to you the power of Silence:

  • Cast Silence upon the party (because companions cannot trigger dialogues while silenced, therefore Minthara cannot trigger her act-traversing refusal dialogue)
  • Then fast-travel back to ACT 1

And now you're free to experience all of the remaining content with Minthara in ACT 1, including the Mountain Pass as well grin
