Crossbow

A crossbow is a projectile weapon. Merlin, having been turned into an assassin by Morgana, asked Sir Leon for a crossbow, wanting to kill Arthur. He found one, but Leon told him that it was ancient and probably wouldn't hurt a fly. Leon then gave him what he called a "thing of beauty", carved from 50-year old ash. Merlin had an impressive shot when he destroyed a barrel with the crossbow. When Merlin told Leon that he was going to use it to kill Arthur, Leon assumed he was just kidding.
