“A sword with which the wielder always strikes twice.”
—In-game description, Shin Monshō
Brave Sword (勇者の剣 Yūsha no Ken, lit. Hero Sword) is a special Sword that has appeared across several titles in the Fire Emblem Series. Forming but one facet of the Brave series of weapons, the Brave Sword, like its other counterparts, possesses the unique ability of granting its wielder the ability to perform twice as many attacks as he/she is normally able to perform, giving rise to the potential for one to strike quadruply. This sword is usually found in the middle or end of any given game, and as such are notorious for being fairly rare.
Coupled with the weapon's unique ability is that of the fact that it is well-rounded, that is to say, it is characterised by substantial Might, supple Durability and a decent Accuracy rate. To this end, this sword thence allows its wielder to gain a tactical edge, and is a good weapon for such slow classes like the Knight and the General. It thus comes as hardly any surprise that this sword is favoured by many a player when they undertake the process of forging weapons.
The only drawback to such a Brave weapon lies in the fact that its Durability has the tendency to deplete rapidly, the result of the consecutive attacks that it induces its wielder to perform. Furthermore, the Brave Sword is relatively heavier when compared with most other swords available.
The Brave Sword is a sword best wielded by Myrmidons and Swordmasters. Of course, any unit (even slower ones) can use Speedwings to improve their Speed and have an increased chance for quadruple the strike opportunities. A good strategy for Brave weapons is to save them for the final battle or for an exceptionally hard enemy unit (usually a boss like Ena or Bryce), because the sword's Durability decreases rapidly (they typically have 30 uses).
In Radiant Dawn, Trueblades can attack a total of 8 consecutive times by using the Skill Adept, a Brave Sword, and having 4 or more Attack Speed higher than the opponent. With the Mastery SkillAstra, it is possible to link up 20 consecutive attacks.
This is possible because:
Having an Attack Speed of 4 or higher than that of the enemy doubles one's hit count to 2.
