Blackmore

Order of Ecclesia
Blackmore appears in a section of Dracula's Castle known as Underground Labyrinth "Flirting with Shadows" as the game's 11th boss. When you encounter him, he will say "I shall take your shadow!", and his own shadow will turn into a demon and start attacking you. His weak point is the shadow he casts, and he is weak against fire & light attacks. Melee weapons will not hurt him whatsoever, so you are better off equipping the Nitesco glyph, which does fire & light damage. His attacks are almost impossible to dodge, so try to hammer him with powerful attacks and have lots of healing items on hand, if necessary.
