You conjure a shard of red-hot rock and hurl it toward an opponent.
As it streaks through the air, a nimbus of arcane energy crackles around it. This spell conjures a small orb of rock and sheathes it in arcane energy. This spell deals 3d6 points of fire damage per caster level. The damage increases by 1d6 per two caster levels beyond first.
If the target is immune to fire, the spell still deals 1d6 points of bludgeoning damage from the force of the conjured orb's impact.
