Level: Bard 5, Mage 5, Sorcerer 5
Range: Visual range of the caster
Duration: Instantaneous
Casting Time: 4
Area of Effect: 2 30-foot radius explosions
Saving Throw: None

When the spell is cast, a red crystal sphere appears before the caster and flies away at great speed towards a targeted area. A split second later, a blue crystal sphere appears and quickly follows behind the red sphere. When the red sphere reaches the area chosen by the caster, it explodes in a fireball 30 feet in radius, inflicting 3d6 points of fire damage plus an additional point for every experience level of the caster to all with in the area of effect. A successful saving throw vs. spell reduces the damage by half. A split-second later, the blue sphere explodes in the same area of effect, inflicting 3d6 points of cold damage plus an additional point for every experience level of the caster upon all within a 30-foot radius. The creatures must make their saving throws separately for both explosions. Note that, as with fireball, premature impact explodes the spheres immediately.
