Ever since the nights of the Second City, the Assamites have fought against demonic forces. Mundane physical weapons normally have no effect upon such ephemeral beings, but Assamite Sorcerers have long-known the secret of enchanting a blade so that it can strike demons.

The Sorcerer first obtains an obsidian dagger with an iron handle. This may be prepared by the Sorcerer or otherwise obtained — the significance is in the composition of the weapon rather than the method in which it is created. Next, she prepares a chamber where no light can naturally enter. This ritual must be cast in complete darkness, or it automatically fails.

The following must be present in the chamber, but can be real or depicted in any way the Sorcerer chooses: a collection of water, representing the primordial ocean, and a block of hardened clay, representing the Sumerian Tablet of Destinies.

The Sorcerer invokes the name of the Sumerian hero Marduk in any way she desires, as long as she is calling upon his aid to strike at the forces of Tiamat, the forces of chaos and darkness. While chanting, the Sorcerer lets the blade taste her blood.

After ten minutes of invocation, if the roll is successful (which also incurs one lethal damage from the bloodletting), the ritual is complete. The obsidian blade becomes completely insubstantial, leaving only the handle solid. The blade now appears as a slowly swirling column of smoke extending from the handle but generally retaining its former shape. It remains in this fashion until a number of sunrises pass equal to the number of successes rolled. Afterwards, the smoke dissipates and the obsidian blade is gone forever (thus requiring a new blade to be obtained for a new casting).

System

Given that the enchanted blade is now insubstantial, it cannot be used in conjunction with Quietus powers such as Baal’s Caress. However, the blade can now strike at incorporeal entities such as demons, ghosts, and spirits when they enter this plane of existence. It passes harmlessly through solid objects and flesh, and thus may be used to strike at possessing entities without damaging the host. Importantly, the enchanted blade may be used by anyone, not just the caster, and the user does not need to know Assamite Sorcery to benefit from its properties. All users do damage with the blade against demons, ghosts, and spirits as though they were fighting a normal, physical opponent.
