I used them to weaken Vrook. I set them up when the rebels attacked. When the rebels were killed I met Vrook, he charged at me and pretty much weakened his HP when he step on some nasty deadly mines.
I agree with that. The masters of all Jedi should try and show the compassionate/forgiving side that they preach so well instead of trying to kill you on sight.
Must be it depends on your influence with the character. A few times he didn't show up.
Plus playing male twice, I didn't have Handmaiden show up once.
