Talking stone

Talking stone was a spell that allowed the caster to speak out of a stone.

Effects
The spell allowed the wizard to touch one stone, and through it, speak and listen out of any stone in Toril he'd previously touched. Neither stone could be enclosed in a magical ward, or the spell failed and was wasted. The spell lasted over ten minutes, more for casters with greater aptitude in the Art.

Components
Besides verbal and somatic components, two different kinds of stone, joined by a wire, were consumed in the casting.

History
Azuth made this spell available through Elminster sometime prior to.
