This device is exactly like a medallion of ESP in every respect, even as to the range it functions at. However, in addition to picking up the thoughts of creatures, it broadcasts the thoughts of the user to the creatures in the path of the beam, thus alerting them. 

Note. it functions correctly, without projecting thoughts, on a roll of 6.

Medallion of ESP. An ESP Medallion appears to be a normal neck chain—usually fashioned from bronze, copper, or nickel-silver—with pendant disc.

The device enables the wearer to concentrate and pick up thoughts in a path 1-ft wide at the medallion and broadening 2-ft every 10-ft from the device the magic reaches, up to an 11-ft maximum width at 50-ft (5"). 

It requires a full round for a character to so use the device. 

The medallion is prevented from functioning by stone of over 3-ft thickness, metal of over 1/6-ft thickness, or any continuous sheeting of lead, gold or platinum of any thickness greater than paint. 

The medallion malfunctions (with no result) on a die roll of 6 on d6, and the device must be checked each time it is used. 

The character using the device can pick up only the surface thoughts of creatures in the path of the ESP area. 

The general distance can be determined, but all thoughts will be understandable only if the user knows the language of the thinkers. 

If the creatures use no language, only the prevailing emotions can be felt—understood only with an ESP-Empathy device (see below). 

Note that undead and mindless golems have neither readable thoughts nor emotions. (See also PSIONICS.)
