Found near the beginning of the Cathedral of the Deep, waiting atop the stairs that lead to the cathedral's outer yard.
Not a very dangerous enemy, although a bit resilient. He often throws firebombs at the player and uses his axe's "Warcry" skill. However, he can only perform one swing at a time, which leaves him open for counterattacks most of the time.
The battle can become quite difficult if the Unkindled Fallen Knight was not dealt previously and is allowed to join the battle, though.
