Shadow Whip

The Blood Whip is Dracula's neutral and main weapon in Castlevania: Lords of Shadow - Mirror of Fate and Castlevania: Lords of Shadow 2. It is a supernatural 'whip' which he creates from his own blood. It has many of the same moves and attacks as the Combat Cross.

Overview
After defeating the Forgotten One Gabriel renounced his old identity and crushed his Combat Cross in his hand. Upon his return to the mortal world he took the name Dracul (but the people knew him as Dracula).

Mirror of Fate
Dracula first displayed his use of the Blood Whip against his then unknown son Trevor, along with the Void Sword and Chaos Claws. In the end he was victorious over his son, to his regret and horror. He would then use it again against his grandson Simon and Trevor, who had been reborn as Alucard.

Lords of Shadow 2
Dracula still possesses the power of the Blood Whip, and this time players are able to control it.

Powers
The Blood Whip manifests as an eldritch red gauntlet on Dracula's right arm. From it the whip springs when he attacks. Like the Combat Cross, it is the only weapon through which Dracula can attain Focus to power the Void and Chaos powers.

Any other abilities the whip possesses, such as the ability to grapple enemies or objects, or alternate means of killing (like the Cross' stake) are currently unknown.
