The spell is cast on a copper brooch. When the spell is cast and the brooch pinned on another individual, the caster can see and hear everything that individual witnesses. If the brooch passes farther away than 1 mile per five levels of the caster, then no information is received. The spell is negated if the brooch is removed.
The spell requires a copper brooch, which can be reused. The brooch can be of any shape or style, but must be made mostly of copper.
Notes: Uncommon for diviners, enchanters, and artificers; otherwise, very rare. (Updated from Polyhedron Newszine.)
