This spell is similar to the psionic devotion psionic sense, except that it uses magical instead of psionic means to gain information. The spell allows the caster to detect psionic activity in a sphere around his location. The diameter of the sphere is 30 feet per level of the caster. Psionic activity is defined as the expenditure of psionic strength points (PSPs).
The caster detects all psionic activity within the area of effect. (In other words, whether or not PSPs were spent in the round by any characters or items within the area of effect.) How much other information he gains depends on his level, as described below.
If the caster is 5th level or lower, he only determines whether or not someone or something within the area of effect is psionically active. A caster of 6th to 8th level also learns how powerful the activity is. Power levels of psionic activity are as follows: low, 1 to 5 PSPs; moderate, 6 to 12 PSPs; high, 13 or more PSPs. (Note that at these levels the power detected includes all psionic activity within the area of effect and doesn't differentiate between individual psionic use.) A caster of 9th to 12th level also learns where the activity is taking place (direction and distance), thus allowing him to identify characters or objects expending PSPs in a given round. Finally, a caster of 13th level or higher can differentiate the power-level expenditure of each individual in the area of effect.
