Range: Close (25 ft. + 5 ft./2 levels)
When you cast this spell, you bring forth one floating, silvery sphere per caster level, each about the size of your head. These spheres hover around you to provide protection from magical effects. As a standard action, you can shift the spell's effect (and thus all the spheres) to any other creature within range. You can shift the effect once per round.
If i interpret the description correctely with a standard action i cast the spell, the spheres pop up over my head and there they stay following me for 1round/level or until with another standard action i transfer them to another target if that target is in Range: Close (25 ft. + 5 ft./2 levels). Right or Wrong?
Furthermore if my interpretation is correct then this spell can be persisted because the initial target is "you" ?
