Khelben's suspended silence

Khelben's suspended silence was an alteration spell that created a field of silence around any inanimate object that was smaller than the caster.

Effects
This spell could be cast on any item smaller than the caster, such as a stone, piece of furniture, weapon or even the corpse of a smaller-sized creature. Once cast, and a command word was chosen, the item was imbued with the magical effects of suspended silence bur remained inactive. This magic left a faint, but detectable aura that could be readily dispelled.

When the item was touched and the command word spoken, a magical sphere of silence, 20' (6.1 m) in radius, emanated from the center-point of the affected object. The sphere moved with the object and remained for approximately 36 seconds.

Components
In addition to verbal and somatic components, this spell required a feather and a handful of dust.

History
This spell was developed by the first Blackstaff, Khelben Arunsun, sometime prior to the Year of Wild Magic, 1372 DR.
