The Dark Devil attacks by splitting into multiple spherical pieces of itself as the pieces bounce along the floor to the other side of the area before reforming, just before shooting a small bullet at Freudia Neuwahl (or Pamela Arwig). When half of its health is depleted, it'll fade away from the area and create a wind while smaller pieces of itself will fly across it from both sides, before the Dark Devil reforms like normal. The Dark Devil's weakness is Eislanze, which is obtained from Luste Teuber. After its defeat, the Dark Devil returns to normal as its previous identity, Eifer.
