The bug bear assassin is indeed triggered by party distance. Having found her dead a couple times during patch 1 I scouted that area around in tactical combat mode, back when you could detach the camera and scout across the map. What I end up doing is sending most my party around the normal windy path way, trigger the combat so tiefling, bugbear, and my three guys stuck in turn base mode. Then have either Gale or Ast, climb/misty step up top from the back way while stealth. You can stealth/climb all the way to the top before being thrown into combat initiative. Then while still hiding back stab the hell out of him or thunderwave him off the back side of that hill.
She does give you a bit of lore regarding the soul coins you find and she gives you one for saving her. I don't know if its on her corpse if you manage to kill the bug bear before it takes off after killing her. If you look through the telescope as the gith it updates your log with the creche location. At least I think it does now I'm wondering if I wished it did or I just merged that into my memory of it being fact. heh.
