The fourth battle

You are the supreme leader of the human resistance and you are battling against the dragaans, after the recent defeat in the third battle your army is very weak and almost entirely gone You are now the wielder of the light blade after an ally gave it to you, the dragaans are attacking the north and you have to stop them however they are fully armoured and have no weak spots to stab or slash, your army uses heavy hammers with a spike on it to break through armour and impale them.
