Anti-Magic Knights fight using the power of Anti-Magic.  Anti-Magic is an energy that is capable of nullifying other forms of magic.  Anti-Magic naturally opposes any mana and magic, so only someone without any magic power can wield it; Therefore, Anti-Magic Knights cannot use magic, however they can gain the benefits of magically imbued items such as healing potions and enchanted items.
