Sonic blast

Sonic Blast
Evocation [Sonic] Level: Sor/Wiz 3 Components: V, S, M Casting Time: 1 action Range: Close (25 ft. + 5 ft./2 levels) Area: 5 ft. wide to close range (25 ft. + 5 ft./2 levels) Duration: Instantaneous Saving Throw: Reflex half Spell Resistance: Yes You generate a deadly beam of sonic energy from your outstretched hand that deals 1d6 points of damage per caster level (maximum 10d6) to each creature within its area. The sonic blast may shove creatures in the area back along the path of the spell. Any creature failing its saving throw must make a Strength check (DC equal to damage inflicted by the spell); those who fail find themselves bull rushed directly away from the caster as if by a Large creature with a Strength score equal to the damage the spell inflicted. The spell moves with the target; see the bull rush description in Chapter Eight of the Player's Handbook for details on attacks of opportunity, stability modifiers, etc. If a creature is shoved back into a solid barrier such as a wall or a strong door, the creature sustains an additional 1d4 points of bludgeoning damage. Like a lightning bolt, the sonic blast damages or destroys objects in its path. If the damage caused to an interposing barrier such as a closed door shatters or breaks through it, the sonic blast may continue beyond the barrier if the spell's range permits; otherwise, it stops at the barrier.
