Into The Breach

[l3v1l33™]

some people have the problem of the door staying shut at the end of this quest. you ask one NPC or your self to stay behind to keep the door open. if your standing on the pressure plate while you talk to a NPC when you go to the door it will be shut and will stay shut. the way to open it is. well. kill whatever NPC is on the plate. they will respawn and try to kill you but if you just run to the boss they can not follow and all is well. just make sure you kill one NPC mainly the archer NOT THE KNIGHT. or you cant complete the quest. this was my experiance i hope it helps.

The easiest way I've found is to have the mage stand on the plate. The door stays open, and the Fateless One and other two go through without issues.

You can persuade one of them to stay behind and keep the door open for you, you know...

yes i know they will stay behind. what im saying is there is a bug where when someone stays behind the door will stay shut. they stand on the plate but the door is shut. i had the archer stay behind and when i went for the door it slammed in my face. i tried everything to get in or around. so i just killed her. when she was off the plate the door stayed open. so kill the NPC problem solved.
