Necromantic singularity

Necromantic singularity was a spell of epic magic.

Effects
When cast, necromantic singularity created a temporary link between the Prime Material Plane, the Weave, and the Negative Energy Plane within 300 ft (91 m) for a very short time. Through this link came negative energy in its purest form and started killing living beings until it was exhausted. It started with those that were closest to the link and went further from the next nearest to the next nearest lifeform until the negative energy was completely exhausted or no lifeform was to be found within 1 mile (1.6 km) of the epicenter.

Components
Necromantic singularity required somatic, verbal, and material components. The material component was a sphere of annihilation that was destroyed upon casting. The spell took one minutes to cast.

History
Bonfire of insanity was one of the most fearsome spells developed on Faerûn. It took the developer twenty-two days and 1,071,000 gp to develop it.
