Gera's Glistening Shards

School:  Evocation [Force]Level 4 Wizard, Sorceror; Level 6 MagusCasting Time:  Standard ActionComponents:  V  SRange:  20 ft. ConeTarget:  20 ft. ConeDuration:  InstantSaving Throw:  ReflexSpell Resistance:  Yes
By use of this spell the caster fires a cone of shards of force in a 20 ft. cone from the caster's hands.  These shards fan out blue shards of chilled force magic striking all within the area of effect.  Each shard deals 1d4 force damage and 1d4 cold damage to any struck in the area.  One shard per level [maximum 5] is released for each possible target in the area.  The caster must roll a ranged touch attack for each target in the area, but only once for each target.  A successful attack roll against a target means all shards flying towards that target successfully strike.  Each target in the area that is struck is entitled to a Reflex saving throw against the effect.  A successful save results in receiving half the total damage rolled for all shards.  Subjects that are protected by a Shield spell are immune to the force damage and only receive the cold damage; though this amount is still halved on a successful Reflex saving throw.
