The Fire-swinger is a type of missile weapon used by searats to ignite and destroy enemy ships, and was used by Greypatch and his crew to weaken the defenses of Redwall Abbey. This weapon consists of a length of rope used as a grapnel, to which is attached a rock covered with grass and soaked in lamp oil. The soaked rock is lighted and swung around in circles to give it momentum, and then hurled by the rope across the wall towards the target. The Fire-swinger appears in Mariel of Redwall.
