SRD:Amulet of Proof against Detection and Location

Amulet of Proof against Detection and Location: This silver amulet protects the wearer from scrying and magical location just as a nondetection spell does. If a divination spell is attempted against the wearer, the caster of the divination must succeed on a caster level check (1d20 + caster level) against a DC of 19 (as if the caster had cast nondetection on herself ).

Moderate abjuration; CL 8th; Craft Wondrous Item, nondetection; Price 35,000 gp.
