Sapphire Drake is an optional boss in Wild Arms 4. The monster first appears in the Cerulean Tunnel after being given a passing mention in the story by Gawn Brawdia as the player party travels through the dungeon. The player is later given an opportunity to fight the monster by talking to the fisherman named Riber in Area 2 of Port Rosalia after defeating the Omen Fish. Riber gives the party a Sapphire Scale that must be brought to Area 2 of Autumn River in order to fight the Sapphire Drake. Upon the monster's defeat, the player will obtain the Sacred Shroud item.
