Tips and Details

  • Aside from its HP, the ability to move independently and not sharing damage taken anymore, the rest of the skill is identical to the standard version.
    • For some reason though, it's PvP damage is much higher, even though its PvE damage is not changed from [Enhanced] Summon Darkness.
  • Due to having its own AI instead of hovering behind Lu/Ciel as it attacks, this version is currently unable to hit Bone Dragon and simply jumps in place in front of it due to a flaw in its hitbox recognition.
