I mean normal Arts. You want Sharla do mostly have Healing Arts on. Don't worry about damage with her. Keep Thunder Bullet on, however. Reyn you want to have Sword Drive and Wild Down maxed out as much as possible. SD does CRAZY damage, WD for the topple. Make sure you're using Gems. Agility and Strength Up for Shulk, HP and Muscle Ups on Reyn, Ether Ups on Sharla,
