Astra (also known as Shooting Star [流星 Ryūsei] or Shooting Star Sword [りゅうせい剣 Ryūsei Ken] in the Japanese versions, Astrum in the European version of Radiant Dawn, Stellaire in the French Version of Fire Emblem Awakening, Fobos in Spanish version) is a skill introduced in Fire Emblem: Genealogy of the Holy War, allowing the user to perform five consecutive strikes, and is also linked to Isaach's royal family (with all members of that family able to use the skill). This skill is also known as Dragon Saint (竜聖の技 Ryūsei no waza, Dragon Sage's Art) in TearRing Saga: Utna Heroes Saga.
In Fire Emblem: Path of Radiance, the skill returns as the Occult skill of the Swordmaster class, but downgraded each attack to deal only half of the intended damage to the enemy. It appears once again in Fire Emblem: Radiant Dawn, where the promotion of a Swordmaster to the Trueblade class will result in this skill being bestowed upon the user, granting him/her the chance to perform a series of five consecutive strikes at full damage. It appears again inFire Emblem Awakening, in its half damage incarnation, learned at level 5 by Swordmasters once more.
In all of the skill's appearances, dodge is rolled for each attack made, and defense is applied to each hit. Starting with Fire Emblem Awakening Weapon durability is only decreased by one for this skill's attack.
