- "The phantom blade. A modest little update from the traditional Assassin's Blade. Where you're going, you may not wish to get too close to your enemies."
- ― Mirabeau explaining the Phantom Blade's purpose to Arno
The Phantom Blade was a modification to the Hidden Blade pioneered and utilized by the French Brotherhood of Assassins. It added a projectile mechanism to the Hidden Blade, making it both fast and deadly at long range.
The Phantom Blade could be loaded with two types of projectiles: a regular projectile blade and a poisoned blade that caused the victim to attack others, allowing Assassins such as Arno Dorian to execute a silent kill or distraction. The Phantom Blade could be upgraded, allowing the user to fire two blades before reloading.
- Around 1501 to 1503, a similar device known as the Hidden Bolt was made by Leonardo da Vinci for the Assassin apprentice Francesco Vecellio. As he was not yet of the proper rank to use a Hidden Gun, the Hidden Bolt acted as a silent alternative which fired small crossbow bolts.
