The wearer of a helm of telepathy could cast the detect thoughts spell at will. While connected to another creature's mind via concentrating on the spell, the helm allowed two-way telepathic communication between the wearer and the connected creature.
Additionally, the helm of telepathy allowed for the wearer to cast the suggestion spell on a connected creature. This power could be used only once per day, as the helm recovered this ability at the next dawn.
