“Raises a nearby ally's resistance. Wears off with time.” —In-game description, New Mystery of the Emblem
Barrier (マジックシールド, Majikku shīrudo, lit. Magic Shield), also known as M Up (Mアップ, M appu) in Thracia 776 and Ward in the recent games, is a recurring Staff in the Fire Emblem Series. When cast, it raises a selected allied unit's Magic or Resistance by a certain amount. The effect gradually wears off with each passing player phase, excluding Fire Emblem Echoes: Shadows of Valentia, where it only lasts for one turn.
This staff also appears in TearRing Saga: Utna Heroes Saga, where it is known as the ☆Magic Staff (まりょくの杖 Maryoku no tsue, fan translated as Ensorcel), and is exclusively bound to Mel.
