After regrouping at the beginning of the match, you enter the tavern. From the entrance, go to the second floor and to the left. There’s a door with a “knock” prompt on it. Press interact to knock on the door. Do it several times and you’ll finish the challenge.

I got it on the 3rd knock 
that one is easy. im struggling to complete challenge modes in randoms.
does anything happen? i’ve done the challenge and knocked a bunch but I didn’t really notice anything besides the knocking sound
I think you have to knock like four times in a row then you’ll hear a spooky ghost noise and the challenge completed thing will pop up
Nothing is happening. Do it several times until “challenge completed” is shown. Otherwise you have completed the challenge.
There is some roaring from behind the door that gets louder with each knock
Does anyone knows how to complete the banshee challenge? The description is vague.
Dont grab the key until u walk around and see all of moiras little dashes around then when it pops up the challenge is completed then grab the key to trigger the fight
ahh thanks
