3D Dot Game Heroes

Dark Knight is a large knight with a sword and shield. He can only be damaged while he is attacking or just after he charges at you. He sometimes shoots a crescent shaped magic attack at you, which you can block with your shield. He also teleports around the room often.

The easiest way to win this battle is to charge the boss as soon as the fight begins. Stand right infront of the boss, block his sword attack, then immediately strike him. The boss will teleport to a different spot in the room, where he will turn to face you, and then shoot a magic attack. Block this, then immediately strike him again. Repeat this until the boss is defeated.
