Castlevania: Lords of Shadow

BOSS: Vampire Dark Lord :

Carmilla reveals her true colors and transforms into her true form as the
Vampire Dark Lord. Additionally, the floor begins to crumble away so that you
are left with a smaller arena to fight on. The Vampire Dark Lord usually
summons about three Vampire Warriors to fight alongside her. Try to defeat
them before you concentrate 100% on the boss. Using some attacks, such as
Flasks, will be able to target both the boss and her minions.

The queen isn't very big, but is quick on her feet and can use her gigantic
wings to float around the room. She has some nasty close-range attacks, such
as some claw swipes and a vicious uppercut that cannot be blocked. Also, the
boss is able to use her needle-like fingers to impale Gabriel. If you are
skewered, repeatedly tap the button onscreen to get free.

If you have any Holy Water Flasks, use 'em at the start of the battle (the
same should be said for a Dark Crystal). Try and use Shadow Magic to defeat
the Vampire Warriors and damage the boss. The Vampire Warriors drop Elemental
Orbs when defeated, so you should have a constant supply of magic.

When the Vampire Dark Lord is down to half a health bar, more of the ground is
destroyed and she begins using two new attacks. Both attacks are preceded by
her taking flight. The boss will either create an energy shockwave on the
ground or summon a pack of vampire bats that swoop down to pester you. If she
is using the energy shockwave attack, jump in the air. If she sends some bats
your way, constantly dodge roll until they disperse.

When the queen is on her last legs, she flies in the air and casts another
protective shield around her before firing bolts of lightning at you. Press
the button onscreen for your Dark Gauntlet to absorb the lightning.

Complete this and the boss falls to the ground, stunned. While she's on the
ground (still inside her force field), use any Dark Gauntlet attack to trigger
the final button sequence. From here, you're only a few short ring sequences
away from exterminating the second Dark Lord.
