Crissaegrim (Lords of Shadow)

The Crissaegrim is the name of the sword used by Alucard in Castlevania: Lords of Shadow 2.

History
After defeating Dracula with the help of his son Simon Belmont, Alucard found the stake attachment of his father's old weapon, the Vampire Killer. Escaping the castle before it crumbled to ruin, Alucard would later forge his powerful sword the Crissaegrim, using the stake as the sword's hilt. The sword was used to stab Dracula through the chest following the fall of the assault on Bernhard Castle by the Brotherhood of Light and its Golden Paladin, as part of a plot envisioned by Alucard and agreed upon by Dracula to defeat Zobek and Satan once and for all. It is unknown what he did with the sword after removing it to ressurect his father, as Alucard is using a different sword, Masamune, in modern times as his disguise as the Lieutenant.

Trivia

 * In Symphony of the Night, the Crissaegrim is the most powerful sword that Alucard can equip.  While it does slightly less damage than the Alucard Sword, it allows you to move while attacking. Also, it swings rapidly allowing you to get in multiple hits on an enemy.
