_________________________________________
You cause a bright ball of flame to boud and skip across the battlefield, damaging targets within its area. The area is the path of the flame, and it deals 1d6 points of fire damage per caster level (maximum 10d6) to all creatures and objects in its area. The flame lights up the area as if it were a torch. Small sparks and decaying flames remain in the area for 1 round, shedding light as candles but dealing no damage.
If the damage from the flame destroys an interposing barrier, the flame can move beyond the barrier if it has no reached its maximum area.
