The ☆Guild Key (ギルドのカギ Girudo no kagi) is a key that is exclusive to TearRing Saga: Utna Heroes Saga. This key essentially functions as the game's equivalent of the Fire Emblem Series' Member Card, as it allows its holder to gain access to Secret Shops. The only difference between the two lies in the fact that while the ☆Guild Key has limited Durability, the Member Card does not.
