Luna smirked slightly as she managed to bash her shield into Sarah's midsection, only to have her own wrist grabbed by the elf and pulled in just as she had done earlier.  Sarah brought the pummel of her sword forward to bash her forehead.  Luna calculated her options as quick as she could as she attempted to pull her head to the side of the pummel.  She couldn't bring her sword forward in time to parry or attempt an attack to make the elf back off... So instead, she jerked the wrist that Sarah was holding toward her person to throw her aim off and bring her closer.  After that, she purposefully took a glancing blow to the side of her head.  It hurt a hell of a lot, but she had to fight through for now.  

Luna then, with a new welt to the side of her head, would bring her head forward to headbutt the elf to make sure the elf lost grip on her wrist and, if successful on that front push Sarah back a small bit before taking the small bit of distance she created to try tackling the elf to the ground.  She hoped that her stubborness in taking pain could out-do the elf's.  Willpower starting to dwindle as her head continued to ache.
