Explosive Cascade

You hold the metal tube out from your body and cast the spell. A bright ball of flame manifests and skips across the battlefield, immolating targets in its path.

You create a path of flame when you cast this spell. Anything along this path takes 1d6 points of fire damage per caster level (maximum 10d6) to all creatures and objects it touches. The flame lights up the area as if it were a torch, and small sparks and decaying flames remain in the area for 1 round, shedding light as candles but dealing no damage. A creature or object can be affected only once by each casting of this spell.

If the damage from the flame destroys an interposing barrier, the flame can move beyond the barrier if it has area remaining.

Material Component: Bat guano, sulfur, and copper packed into a metal tube with one closed end.
