In Hyrule Warriors: Age of Calamity, Lightning Rods are tools that can be wielded by all Warriors, as well as by enemy Electric Wizzrobes. Located on the left bumper wheel with the Fire Rod, Ice Rod, and Apple, Lightning Rods are limited charge attack Items that will shock anything in its attack radius. They can also help whittle away at exposed Weak Point Gauges. This attack radius can be widened if Enemies are near metal crates or are in Water. The Lightning Rod need Electric-elemental energy as fuel for its attacks, and the amount of charges the Rod has carry over into future battles, meaning completing battles with an empty Lightning Rod will have the Lightning Rod remain out of charge. The energy needed to power the Lightning Rod can be found by either slaying Electric Monsters, such as Electric Wizzrobes, or by smashing open crates.
The Lightning Rod is obtained by slaying the player's first Electric Wizzrobe, with the first one being found in the "Road to the Ancient Lab" Scenario. The Lightning Rod help make the Weak Point Gauges of certain Monsters, such as Waterblight Ganon], drain faster. Being hit by the Lightning Rod while near or on a conductive surface will allow Warriors to chain Weak Point Smashes more consecutively.
While the Lightning Rod innately has three charges, completing the "The Research of Rods" and "It Takes Two" Quests both reward Warriors one additional charge to all Rods, including the Lightning Rod.
