Knight

Knight is a tier 3 melee class, its a straight upgrade to the swordsman with the only difference other than stats is the fact the knight has a shield.

They can tier up into:
 * Paladin
 * Templar

Strategies
Both this unit and its tier ups are mainly used as tanks, meaning that they are the main strenght of most teams yet its better to get some more knights or swordsman tier ups alongside as well as other long ranged units.
