At some point during several of my run-throughs, Roah and her two guards have retreated inside the treasure room that they start out guarding. This is a pain because you can't get close enough to her to start trading without stepping into the treasure room, which starts combat. I suppose I could try to pick up Minor Illusion to try to lure her near the doorway, but that doesn't work well when I have tried.
Does anyone know the trigger for her retreat? I usually do several things at once in the Shattered Sanctum, so I don't know which one makes her go into the room. Could be: releasing the spiders, starting to kill the goblin leaders, or stealing all her treasure.
