Flamespitter [Mount]

This ceramic and metal contraption features a great deal of armor protecting the fuel tank.
Benefit: While mounted, you can fire a Flamespitter as a standard action, inflicting 1d4 energy damage with the [Fire] descriptor per level to all opponents in a 10-foot-wide line originating from yourself out to [Close] range. A successful Reflex save (DC 10 + 1/2 your level + your KOM) halves the damage. You may grant the mount a bonus to its movement speed for its next movement this [Round] equal to 5 ft per opponent caught in the line.
