This guy can be pretty hard. The biggest problem is that his sword attacks' hitbox stays active for a second or so AFTER the attack is finished, so dodging should be done carefully. He also has several lightning projectiles, which are easily dodged (note that a wave of several lightning balls should be dodged by rolling THROUGH it).
But wait, there's more! After his HP his 70% mark, he will start using his mirror to summon phantoms, and if you're really unlucky, the phantom will be an actual player.
