Components: V, S

Range: close (25 ft. + 5 ft./2 levels)
Target: 1 creature

Saving Throw: Will negates, see text
Spell Resistance: yes
  You overload the target creature's senses, making it difficult for the target to concentrate. For the duration of the effect, the target must succeed at a Will Save at the same DC as the original effect to perform any standard or Full-Round Action. On a failure, the creature loses the action that triggered the saving throw. If successful, the creature is able to take the action, but this spell effect is not negated.
