Sense Psionics

Sense Psionics or "Psi Sense" is the ability to detect the use of psionic activity, energy, and ability. Psychics who specialize in this power (sometimes called a Sniffer), can use this skill passively (i.e. it is always "on") and will automatically alert the psychic that psionic energy is present—much like a Geiger counter would detect radioactivity or the hairs standing up on one's arm might indicate strong static electricity.
