is it possible to only deploy the crew who aren't going to be killed? Will that be enough to defeat Arihama? And also about Dylan's brother, if I choose not to tag him along, there won't be any consequences right?
You can choose not to tag Rylan's brother. (The consequence is that he will remove some like points from you, also he (Riordan) would recommend that you should pull Rylan from the battle.)
