Summoning
To summon the Dark Knight, the player needs to craft the Fallen Hero Sword. He can be summon at anytime above ground excluding the Ocean biome.

Stage 1
The Dark Knight is a slow moving boss who attacks by swinging its sword, if the player is too far from the boss, it will leap towards the player, going through blocks, and when it hits the ground it will send a shock wave for 10 blocks that deals 50 damage. If the player is not on the same plane as the boss, a dark hand will reach out and pull the player towards the boss. Every 10 seconds the Dark Knight will spawn 5 buffed Possessed Armors which have double stats.

Stage 2
After the Dark Knight reaches half health, its armor burst off and hovers over its new form, which looks like a wraith with a purple tint and twice its size. In this form its armor is reduced to 0, its movement speed is doubled and it flies. The armor will sometimes fly at the player, dealing 50 damage and stunning them for 2.5 seconds.

Stage "3"
In expert mode the Dark Knight can teleport onto the player and its armor, instead of flying, because a second entity, a copy of the first stage but twice as slow, it's also unkillable, killing the second from will kill the armor.
