If yhwach paralyzes renji you can obtain some seconds but still stay close to the exit
Those 2 normal attacks (or a strong attack) + third strong attack on Rukia are needed in order to instantly kill her with special (preventing her special to destroy your shield) - if she gets paralyzed you can quit the run since she won't be weakened by yhwach's special
If yhwach weakens ichigo with normals and strong attacks it becomes easier too
