The original 2nd Edition entry from the Forge.

This powerful item is contained within a small coffer approximately 4"x6"x4". The coffer is made of an unknown metal tarnished black with soot. It has a simple latch with no lock. The coffer blocks the effects of the Stone.

When exposed, the creates an area of dead magic in a 50' sphere. Any and all magic is completely negated as long as the stone is exposed. The stone will negate all spells entering its area of effect and end any spells being maintained. Magic Items also temporarily lose all enchantments while exposed to the stone.

The stone was used in the great battles at Mythril Hall and caused the deaths of many worshippers of the Spider Queen Lloth. The stone is currently believed to be in the possession of a glabrezu in the Abyss.
