Legend's Crossbows are Linkle's Level 3 Crossbows from Hyrule Warriors and Hyrule Warriors Legends. They are a pair of ornately designed Red & Blue Crossbows that have a Fire Elemental Attribute. Linkle wields the Red Crossbow with her right hand and the Blue Crossbow with her left.
The red crossbow has a sharper and angular design with a Flame Design where the bolt sits. It is directly based on the Bow of Light wielded by Princess Zelda in The Legend of Zelda: Twilight Princess. While the blue crossbow has a softer rounded design with a circular object with two notches on it where the bolt sits. The red and blue designs on the crossbows are reminiscent of the Fire Arrow and Ice Arrow.
Legend's Crossbows + is Linkle's Level 4 Crossbow in Hyrule Warriors Legends. It is basically a stronger plus version of her Level 3 Crossbow. Like all Level 4 weapons, it has the same design as the Level 3 weapon it is based on.
