Medallion of Thought Projection

This device seems like a medallion of thoughts, even down to the range at which it functions, except that the thoughts overheard are muffled and distorted, requiring a DC 15 Will save to sort out. However, while the user thinks she is picking up the thoughts of others, all she is really hearing are figments created by the medallion itself. These illusory thoughts always seem plausible and thus can seriously mislead any who rely upon them. What’s worse, unknown to her, the cursed medallion actually broadcasts her thoughts to creatures in the path of the beam, thus alerting them to her presence.

Prerequisites: Craft Wondrous Item, detect thoughts, ghost sound.

Cost to Create: 900 gp, 72 XP, 2 days.
