AC0 Magic Item – The Breath of Katenga

The Breath of Katenga is a unique and powerful brass tube with a sturdy wooden handle. It is adorned with intricate etchings of ancient runes, hinting at its magical nature. Attached to the wooden handle is a glass trigger, designed to be easily operated with a single finger. Adjacent to the trigger, you will find a small glass container filled with water, crucial for the device’s functionality.

At the base of the brass tube, there is a dial that allows you to adjust the diameter of the barrel. By turning the dial, you can manipulate the size and power of this wondrous contraption. The device can be used both as a formidable defensive weapon and an offensive tool, relying on the power of steam to unleash its might.

To employ it defensively, turn the dial to its maximum opening. When the trigger is held down, the water within the glass container will be released, transforming into a colossal cloud of steam. This fog spreads over an area of 30 feet in width, 5 feet in thickness, and rises to a height of 10 feet. The dense steam obstructs vision and hampers the movements of those caught within, providing a significant defensive advantage.

When utilized as an offensive weapon, twist the dial to its smallest setting. Once the trigger is activated, a concentrated jet of scorching steam is propelled forth from the brass tube. This jet of steam has a range of up to 30 feet and inflicts 1d6 damage upon its target. This destructive capability can be executed thrice in a single round for a total of 1d6 damage per shot or once for a devastating 3d6 damage.

It is important to note that when used offensively, the glass container can endure up to 9d6 of steam damage before it must be promptly replaced, which takes approximately one round to accomplish. Conversely, when utilized in a defensive manner, the glass container needs to be replaced immediately after the fog is discharged.


The creation of the Breath of Katenga is a process that demands both skilled craftsmanship and the infusion of magical energy. Crafting such a powerful magic item requires the expertise of a master artisan and a skilled enchanter working in tandem.

The first step in creating the Breath of Katenga is the construction of the physical components. An experienced metalworker begins by fashioning the brass tube, carefully shaping it to have the desired length and diameter. The tube must be meticulously crafted, ensuring that it is both sturdy and functional. Once the tube is completed, it is given a smooth finish, ready for engraving.

At this stage, a skilled rune master takes over, etching the surface of the brass tube with intricate and precisely drawn magical runes. These runes serve as conduits for the magical energy that will ultimately power the device. Each symbol is carefully placed, representing the spells and enchantments required for the Breath of Katenga’s manifestations.

Simultaneously, a talented woodworker starts crafting the handle from a solid piece of fine wood. The wooden grip must be ergonomically designed and seamlessly attached to the brass tube. Once the handle is securely connected, attention is turned to the glass components.

A glassblower carefully crafts the delicate glass trigger and container that houses the water necessary for the device’s functioning. The glass trigger is formed to be easily gripped and operated, facilitating swift and precise activation. The container is designed to securely hold an ample amount of water and seamlessly integrate with the overall structure of the device.

After the physical components have been completed, the time comes to infuse the Breath of Katenga with magical energy. An enchanter skilled in the manipulation of arcane forces works alongside the artisan. Through a combination of complex rituals, incantations, and the harmonious fusion of magical ingredients, the enchanter imbues the device with its power.

The enchanter channels raw magical energy into the engraved runes, awakening their dormant potential. The runes then become conduit points for the spells and enchantments inscribed upon them, enabling the Breath of Katenga’s defensive and offensive capabilities.

This intricate fusion of craftsmanship and magical energy culminates in the completion of the Breath of Katenga. The result is a powerful, versatile magic item that harnesses the elemental force of steam.
