As Luke took care of a few of those Autons, Mara landed on the ground briefly, before she once again leapt into action. She was taking a more classic melee fighter approach to this rather than using her Force abilities. If only because it did help her vent some of that inner storm. She knew she could easily handle these things using the Force, but she wanted the satisfaction and release of dealing the damage with her own lightsaber.
And so as she once again flipped through the air, she arched her lightsaber outwards at the things, severing a few heads. When she landed on the ground, only three remained. And that was when she finally used a Force ability. She used the Force to push the Autons back, knocking them over and keeping them from shooting either her or Luke.
"Would you like to finish them, love?" Mara offered, looking over at Luke.
