Wall of Lightning
Evocation  [Electricity]  {Chagode, Tapas}
Level: Sor/Wiz 7
Components: V, S, F
Casting Time: 1 action
Range: Medium (100 ft. + 10 ft./level)
Target/Area/Effect: Semi-transparent plane of electricity whose
  area is up to one 10 ft. square/level
Duration: Concentration, then 1 round/level
Saving Throw: Reflex half
Spell Resistance: Yes
You create an immobile wall of electrical energy. One side of the wall, selected by you, strikes creatures that approach within 60 ft. with bolts of lightning, dealing 5d6 points of damage. The wall deals this damage each round that the creature remains within striking distance. In addition, the wall deals 1d6 points of damage per caster level (maximum 15d6) to any creature that attempts to pass through the wall.
    If you evoke the wall so that its plane bisects the location of any creature(s) then each creature within the wall may make a Reflex saving throw to move to the safe side of the wall and suffer no damage. Creatures that fail their saving throw are caught within the wall, take damage as though they were attempting to pass through it (1d6 damage/level, max 15d6), and may choose to move out of the wall on their next turn.
    Focus: A bar of iron that has been struck by lightning.
