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. Typically made of either basic metals or more valuable ones such as gold and silver.

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.

Heavy aspergillums were designed as a sort of melee weapon, with an effectiveness equivalent to that 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 both gold and silver varieties of chained aspergills.
