A knight's need is a combination of four items: a SHIELD, a MOUNT, a LANCE, and a STEED. A SHIELD is a protective covering used to deflect blows from weapons, typically made of metal or wood. A MOUNT is a horse or other type of animal that a knight would ride into battle. A LANCE is a long spear-like weapon used by knights in jousting tournaments and on the battlefield. Lastly, a STEED is another word for a horse, which was the primary mode of transportation for knights.
