Onyx wasn't able to get her arm from his grip. She had felt him loosening but he used his other arm to keep his grip and then started trying to trip her. Onyx decided to change tactics as she had to focus more on not tripping. She stepped as close to him as she could, racking her claws up his wrist as she did and turning so that her back was to him and both his arms were in front of her. she grabbed both his arms with both of her own, digging her claws into his wrists but not drawing blood, and slammed her back into him, hoping to knock him over and finally get out of his grip.
