By uttering the phrase “tat tvam asi” (“that art thou”), the caster's senses become one with all beings and objects within a 30' radius sphere centered on the caster. The caster sees and feels everything sensed by every person, caterpillar, tree, and rock in the area of effect. (A first-time caster will be surprised how much a rock feels.) The onrush of sensory information allows the caster to know of all beings and objects in the area, including hidden and invisible creatures, traps, and magic items. The caster does not sense thoughts or detect powers of creatures and objects contacted. Because the spell accesses thoughts, any being whose thoughts are masked cannot be spotted solely with this spell. While the spell is in effect, the caster can take no other action, including movement and speech. The caster can discontinue the effect at any time during the spell's duration.
Notes: Common for priests from a vedic (Indian) culture; otherwise very rare. (Updated from Dragon Magazine.)
