Arc Rejector was created from modified Arc Projectors. But in order to make the Heavy Weapon more effective the polar connections were changed places and except of releasing the energy Arc Rejector absorbed the energy and converted it into Ion blast which destroyed weakened enemy. Oblivion Hunters made use of this weapon during the Inquisitor Crisis when it was used on Citadel and Omega. Synthetic parts of Inquisitors were powered of a Ion blast burned of the organic parts. After it the schematics made it the most valuable weapon in galaxy. Merchant from Citadel to the lawless Nemean Abyss bought tons of this weapons. And it became the main source of finances on the construction of Drell Haven on Shakrahna.
