is there any walkthrough or study aiming the fastest way (without lone wolf) to open the room of the secret vendor?

The fastest way I mean is that by the lowest level (without lone wolf) to open the room of the secret vendor.

Now, I can open the room just with one character level 2 and the other level 1. But I am curious if I can open it with both of my character level 1.

Even if there is by no means possible that both character level 1 could open the room, I still wanna read the article about the others' walkthrough aiming opening the room with the lowest level as possible.
