If the target of this spell fails to resist its effects with a Will save, he becomes outlined in faint radiance, as if via faerie fire. At any time before the eldritch conduit expires, you may cast another spell with an area effect of cone, cylinder, line, or sphere and use the subject of the eldritch conduit as the point of origin for that spell. Doing so ends the spell immediately. The target must be within close range (25 feet + 5 feet/2 levels) in order for you to use the conduit—if the target moves out of range, the eldritch conduit effect persists but cannot be utilized by you until you get back within range.
Range medium (100 ft. + 10 ft./level)
This spell functions like eldritch conduit save for the differences listed above and that the target must be within medium range (100 ft. + 10 ft./level) in order for you to use the conduit. Using a creature as a conduit for a spell ends the greater eldritch conduit effect on that creature, but does not end the effect for other eldritch conduits.
