Do you have to fight all her sisters to get her? Just curious, because my sentinel got beat down by a bunch of girls.

if you're a male, you get her after you leave telos.

 

but if you're female, you dont get her at all. but you do get the disciple on dantooine

So you don't have to fight her sisters? Do you get anything for beating all five?

 

Oh, and thanks for the reply.

You get a piddly amount of experience. I was around level 12 when I beat them and received 750 for my grief. The Mandalorian battle circle is much more generous

 

Easiest way to beat the five sisters is to run to the far corner of the mat once combat starts (while staying as close to the edge as possible), with luck two or three of the sisters will run around their sisters and off the mat trying to get to you.
