Oozinator (3.5e Equipment)
From D&D Wiki
The Oozinator is a vaguely gun-shaped object held in one hand. It fires streams of "ooze" at the opponent. At will you can create the effect of a Grease spell, with a DC of 12. In addition to slimy grease, it can fire more caustic ooze with the effect of an Acid Arrow spell at will.
For an additional 100g, you can attach an Oozinator to any gun-shaped object such as a crossbow, and use them in tandem.
