Description: A divino-matic rod is a 2-foot long hollow iron staff with a crystalline tip held in place by a swirl of copper wires. Four metal prongs extend from the sides of the crystal's base. When the rod is activated, arcs of electricity jump about the prongs. The goblins of the Tanaris Desert developed this device to help locate underground sources of water, but one of these rods could be used to find many sorts of useful materials.
Operation: A divino-matic rod can detect the presence of certain substances. The owner adds a small quantity of a given substance to a compartment within the shaft, activates the item (with a DC 15 Use Technological Device check), and holds it out. Each round, the sparks that fly from the crystal point the way towards the largest nearby quantity of the substance in question. The rod has a range of 200 feet.
Activating the rod and changing the substance within the rod's compartment are separate standard actions that provoke attacks of opportunity.
The substance can be any single element, rock, alloy or simple compound, such as gold, copper, water, alcohol, phlogiston, salt, granite or bronze. The rod cannot detect living or organic things, such as a particular type of plant or a dragon's scale. As always, the GM is the final arbiter on what does and does not function in a divino-matic rod.
If the bearer searches for an alloy or compound, nearby elements of that substance can throw off the check (and vice versa). For example, if a warrior in plate mail is standing next to the wielder and he searches for a source of nearby iron, the rod may wind up pointing directly at the warrior (since iron is a component of steel).
Fuel: A divino-matic rod uses 1 vial of liquid phlogiston for every 2 minutes of continuous use.
Malfunction: The device overloads, dealing 3d6 points of electricity damage to the wielder, and doesn't function again for 24 hours.
