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).

Prerequisites: Craft Wondrous Item, nondetection.

Cost to Create: 17,500 gp, 1,400 XP, 35 days.
