The Firesweep Sword (火薙ぎの剣) is a sword that appears in Fire Emblem Heroes.
The Firesweep Sword is a potent generic offensive weapon in allowing the user to attack without fear of being countered, as it removes the enemies' ability to counterattack. At the same time, however, if the wielder is attacked, they will be unable to counter in turn; the key element of tradeoff for the sword.
Firesweep Sword can be learned without inheriting by Soleil.
Unit and enemies cannot use counterattacks.
- Due to the length of the name, in-game Firesweep Sword+ is shortened to Firesweep S+.
