The Flame Shuriken (爆炎手裏剣 Bakuen shuriken, lit Explosive Flame Shuriken) is a Shuriken introduced in Fire Emblem Fates. Like its name suggests, the Flame Shuriken is imbued with the element of fire, drawing on the Magic of its wielder to singe its foes with magical flames. Apart from raising its wielder's Speed by 2, the Flame Shuriken also reduces the enemy unit's Magic, Defense and Resistance by a fairly substantial extent post-battle.
The Flame Shuriken is particularly useful for Felicia, who has very poor strength growth but good magic growth. It is useful for any shuriken-using class for taking on more physically-oriented classes, such as Knights.
The shuriken (手裏剣) was a common throwing weapon for ninja, and its name can mean "sword hidden in the hand", or "the sword inside of hand". These were flattened, bladed discs that were thrown at enemies.
