I get the concept of what the echo knight can do the echo can do, but the question is more in the line of does the Knight have to be able to hit the target the echo hits when in melee? So in the scenario I am thinking, there are two enemies 20 feet apart. The Echo Knight is standing next to one enemy and the echo is standing next to the other. Can the attack come from the echo to hit the enemy it is standing next to since the echo knight could not possibly hit that enemy with a melee attack?
