Unfortunately for Auz, Xaviers footing [b][i]had[/i][/b] been secured a few moments before. Upon his prior movements Xaviers right foot had been cradled by the puddle both men stood on. Ontop of this his left foot would be back on the ground by this point. So when Auz pulled  the sword towards himself Xavier stood firm. The tugs power swayed Xaviers upper body only slightly before he returned the power. Utilizing his superior footing to allow him to pull back on the sword. Xavier was not trying to pull Auz into him. Rather he would be hopefully preventing Auz from gaining or losing an inch of footing by. Leaving him almost no remaining time to dodge the impending spike which would still be careening for his taint.
