Iron Knight

Iron Knights are strong knights covered in armor.

They were Armored anti-armored on the computer, then switch to Armored anti-light on mobile.

Computer
Iron Knights are perfect if you want a large group of armored units in the late game. They have more HP, Move Speed and damage than Immortals, meaning a swarm of Iron Knights can easily defeat Dread Lords. Iron Knights are also very useful at tearing apart Cavalries and Mages.
