Demon Zapper

The Demon Zapper is a feat a infernal engineering located on the plane of Avernus in the Nine Hells that was created in Bel's Forge. The Demon Zapper is a 10 ft. diameter sphere that is powered by a unicorn imprisoned inside that can shoot bolts of radiant power at any fiend that gets within 100 ft. of it.
Located on the contra-Abyss side of the River Styx, it was originally designed as a weapon to attack demons when the tide of the Blood War favored the forces of the Abyss. However, it's inability to distinguish between infernal and abyssal fiends means that it was abandoned when the front line of the Blood War advanced Abyssward.
