Alchemy

Alchemy, as explained by Rinaldo, is the field that experiments with the principles of God's creation of the world. Not many know about the existence of alchemy and it is usually referred to as a heresy.

Crimson Stone
One of the two greatest treasures of the vampires. Stone allows its owner to use the soul of a vampire as a power source. Unfortunately it bears the curse of the vampire so a human using it would also become a vampire. It was believed to be lost along with Ebony Stone.

As it turned out, Mathias actually possessed it, and used it to absorb Walter's soul (after Leon had defeated him) by doing so he achieved his ultimate goal- eternal life.

One additional benefit of the stone is that Death offers his allegiance to whoever possesses the Crimson Stone.

Ebony Stone
Second greatest treasure of the vampires. It causes its surroundings to be enveloped in a never-ending night. Possessed by Walter and later by Dracula.

Philosopher's Stone
The ultimate goal of alchemy. It provides eternal youth. The Ebony and Crimson Stones were created accidentally while attempting to create this stone. It is not known if it was ever made successfully.

Whip of Alchemy
A whip created with alchemy. This was the original form of the Vampire Killer Whip. Created by Rinaldo who was unable to use it to its full potential. He gave it to Leon Belmont, who was still unable to use it fully.

When Sara became cursed by the Walter, she sacrificed herself to its mercy and her soul joined with it to form the Vampire Killer Whip.
