After one enters a stance employed by a fighting style a style feat embodies, is there any condition, effect, or situation caused by an outside force that can cause one to drop or end the stance? (Style Feats, Ultimate Combat, pg 78) Example: A monk is first to act in combat, he has all three of the Crane Style feats. He uses a swift action to adopt the stance from the Crane Style. Does he remain in this stance until he dies and/or combat ends? Or is there a way an outside force can cause him to drop the stance?
