Aspergillum

An aspergillum, also called an aspergill, was an implement used for spraying holy water.

Description
Aspergillums came in various designs, but often took the form of a small metal club or light mace, sometimes hanging on the end of a chain. Each had a reservoir inside that would contain a quantity of holy water, ranging from one to three flasks' worth (1–3 pints, or 0.47–1.4 liters). Pressing a button on the shaft opened up the perforations in the head, allowing holy water to leak out. Alternatively, an aspergillum on a chain could be swung or whirled to spray out the holy water. In this way, the aspergillum could spray holy water over a short distance, using one flask's worth per shot, but over a greater distance than simply throwing or pouring it.

They could be made of basic metals (costing 5 gp), or of silver (20 to 50 gp) or gold (45 gp).

The heavy aspergillum was designed as a melee weapon, with the effectiveness of a heavy mace.

Uses
The aspergillum was used by priests to sprinkle holy water and dispense the power of their god, whether in blessing or spellcasting, in both the temple and on the battlefield. Many adventurers employed them too, for simply spraying monsters with holy water.

Aurora's Emporium sold chained aspergills in both silver (20 gp) and gold (45 gp) versions.
