During any exchange, your side can try to create advantages before making your overcome roll. The target, or anyone else who can reasonably interfere, may oppose with a defend roll as normal. Each participant may attempt to create an advantage in addition to rolling or providing a teamwork bonus (page XX). If you fail to create an advantage, you have a choice: either your side forfeits its overcome roll, or you may “succeed at a cost” (preserving your roll or teamwork bonus) by giving the other side a free invoke instead. If you at least tie, proceed as normal with your roll or bonus.
