Acid Spray Gun

Acid Spray Gun (Recharge 5–6). As an action, this device can be activated to spray acid in a 10-foot cone. Each creature in the area must make a DC 10 Dexterity saving throw, taking (2d6) acid damage on a failed save, or half as much damage on a successful one. It cannot be used again until it recharges. At the end of each turn, roll a d6 to determine if the device recharges.

The spray gun has a tank that can be filled with ten standard acid vial mixed with water, allowing it to be used five times.
