The shovel may rule the confines of man-made gardens, but in the wild, the titan of tunneling is the mole! Mole Knight embraces this truth wholeheartedly. With his modified drop-forged armored claws, he mockingly tears through the earth with brute strength! Mole Knight calls the subterranean Lost City his home... an ancient abandoned metropolis. Shovel Knight must pass through the Lost City, but chances are slim he won’t be challenged to see who is truly the master of digging.
Mole Knight is a very high-mobility boss. It is difficult to do much damage to him in one go. When the fight begins, he will shoot out of the walls at high speed in an attempt to ram into you. The best thing to do in this phase is to charge up your Shovel, and attack him with it when he comes towards you, as this will negate his attack and damage him at the same time. After shooting out of the walls a few times, Mole Knight will land on his belly and slide across the ground, with his armor shooting out sparks from grinding against the ground. After this, he will dig up blocks to launch at you; the stacks of blocks he sends at you get progressively bigger the lower his health is. If you manage to get on top of him and Shovel Drop onto him, you can rack up a lot of damage on Mole Knight as he is stationary during this attack. After doing some damage to him, he will burrow underground and hide under one of four dirt piles. It is easy to find which one Mole Knight is under, as his visor will be peeking out. Digging this pile up stuns him for a short time, but watch out as a mole enemy is hiding under another pile and will damage you. After he emerges from the ground, he will call down magma to cover him, and he launches balls of magma which loosely track your movement while drops of magma fall from the ceiling. He is invincible while this attack goes on, so stay away from him and try to dodge the balls of magma. You can, however, hit some of the balls of magma back at him for a little bit of damage; the flashing magma balls do extra damage. When this attack ends, Mole Knight will stomp the ground to make some dirt blocks fall from the ceiling, and then he'll repeat the entire cycle.
In Specter of Torment, Mole Knight's battle is largely the same, but the dirt blocks he attacks with are replaced with green slime blocks. Also, he now covers himself in green slime instead of magma, which makes him able to attack by bouncing around the room until the slime wears off.
