A Conductor, also known as a Lightning Orb, is an object in Mario & Luigi: Superstar Saga and its 3DS remake, Mario & Luigi: Superstar Saga + Bowser's Minions, being the opposite to Torches. They are blue spheres that are first seen in Oho Oasis. Conductors can be found in various locations in the Beanbean Kingdom and be powered by Luigi's Thunderhand (as opposed to Torches, which are lit by Mario's Firebrand), which opens up pathways leading to new areas. The Conductors in the repaired Koopa Cruiser can reveal hidden ? Blocks containing multiple Hee Beans once powered.
