Nitro Blast

Using this spell, the caster is able to burn more fuel for greater speed and to cause flames to erupt behind the vehicle in the form of a deadly cone attack. Any creature or vehicle caught in the area of effect suffers 1d6 points of fire damage per level (max of 15d6), which may be halved with a successful Reflex save. The touched vehicle’s speed increases by 10 feet per d6 of fire damage. The Drive check penalty of the vehicle is also increased by 4, but its initiative bonus increases by 2.
