Appendix A: Rules for Splashing Weapons

Buckets:
As an action, a character can fill a bucket with liquid from a pool or tank. Filling a bucket from a tap or well takes about one minute. A character can heave the contents of a bucket at creatures within a 5-foot square. If the target creatures are unwilling to be soaked, they must succeed on a Dexterity saving throw or be drenched in the liquid.

Hand-Pumped Fire Extinguishers:
These brass syringe-style water guns come in three sizes: 1-gallon, 2-gallon, and 5-gallon models. The larger extinguishers require a Strength score of at least 12 or 14, respectively, to be operated by a single creature when full.

As an action, the extinguisher’s nozzle can be placed in a tank or pool of liquid, and the handle extended to draw a full charge. As another action, the user can shove the handle to project a 30-foot-long, 5-foot-wide line of liquid.

Creatures in the line must make a Dexterity saving throw to avoid being struck. On a failure, they are soaked.

Hand-Pumped Fire Engine:
A large, cart-mounted pump fitted with a hose and brass nozzle. The engine requires at least three creatures (ideally five) to operate: two or more to work the pump and one to aim the nozzle.

To operate, the engine must be parked. At least two creatures must spend their actions to pump while another uses their action to direct the nozzle, producing a 30-foot cone of water. If four or more creatures are pumping, the spray increases to a 60-foot cone.

As an action, the creature wielding the nozzle can adjust the output to a line 5 feet wide and up to 80 feet long instead.

Creatures caught in the cone or line must make a Dexterity saving throw or be soaked and pushed 5 feet back.
