Knights are one of the best units in Conquest. They can be used as a good defensive unit, as much as a Foot Soldier, so they can likewise hold a defensive position. They have the advantage of 300 attack, allowing them to rip apart any unit apart from a champion from its initial state, and can even kill one with the help of Battle Cry. They can also be used as a substitute for a champion in the "Devastation" tactic (see Conquest/Strategies).
These are good all round troops, much like the halberdier, and at only 100 command points each can prove a worthy addition to many an army.
