SRD:Reveal (Epic Spell Seed)

The caster of this seed can see some distant location or hear the sounds at some distant location almost as if he or she was there. To both hear and see, increase the Spellcraft DC by +2. Distance is not a factor, but the locale must be known—a place familiar to the caster or an obvious one. The spell creates an invisible sensor that can be dispelled. Lead sheeting or magical protection blocks the spell, and the caster senses that the spell is so blocked. If the caster prefers to create a mobile sensor (speed 30 feet) that he or she controls, increase the Spellcraft DC by +2. To use the reveal seed to reach one specific different plane of existence, increase the Spellcraft DC by +8. To allow magically enhanced senses to work through a spell built with the reveal seed, increase the Spellcraft DC by +4. To cast any spell from the sensor whose range is touch or greater, increase the Spellcraft DC by +6; however, the caster must maintain line of effect to the sensor at all times. If the line of effect is obstructed, the spell ends. To free the caster of the line of effect restriction for casting spells through the sensor, multiply the Spellcraft DC by x10.

The reveal seed has a base Spellcraft DC of 25 if used to pierce illusions and see things as they really are. The caster can see through normal and magical darkness, notice secret doors hidden by magic, see the exact locations of creatures or objects under blur or displacement effects, see invisible creatures or objects normally, see through illusions, see onto the Ethereal Plane (but not into extradimensional spaces), and see the true form of polymorphed, changed, or transmuted things. The range of such sight is 120 feet.

The reveal seed can also be used to develop spells that will do any one of the following: duplicate the read magic spell, comprehend the written and verbal language of another, or speak in the written or verbal language of another. To both comprehend and speak a language, increase the Spellcraft DC by +4.
