She has health, there must be someway even if it is pointless.
Maybe keep a friend in that room and let the doors lock them out?

I almost killed her in fist of Crota when she is outside fighting the fallen. I kept stunning her with icebreaker head shots, got her down to quarter health and ran out of ammo. She teleported away. Might be possible with black hammer or full fireteam

She's immune once in the room. Had a friend in there, he got killed quite fast and couldn't be rezzed.
-
No, she is immune. Also if someone stays on the room the doors stay open iirc

No she's immune in that room my friend did it when he was lagging super bad ha
