Rienfleche (リヤンフレチェ Riyanfureche) is a daunting Bow that appears exclusively in Fire Emblem: The Blazing Blade. Rienfleche is unrivalled by its other bow counterparts, and is the fourth most powerful weapon in the game overall.
- It appears as though the name of this weapon, comprised of the French rien, "nothing", and fleche, "arrow", is a misrepresentation of Royalefleche, meaning "royal arrow", which would have been more in keeping with the names of the Regal Blade, Basilikos and Rex Hasta. It could also have meant to be called Roifleche, meaning "king arrow", or Reinefleche, meaning "queen arrow".
- Rienfleche's in-game description states that it can strike consecutively in the same way as a Brave weapon, but this is false. If the effect were to actually work, it would probably be the best S-ranked weapon in the game, and would also surpass Radiant Dawn's Double Bow minus its range of 1~2.
