A crack in the ground, starting at the caster, runs for 18" in a straight line. Any models in its path must roll equal to or less than their Initiative to leap out of the way (6 always fails). If they fail they fall into the crevasse never to be seen again. War engines, chariots, etc must roll 5 or 6 or be destroyed. Buildings affected suffer D6 damage points.

This spell works in a comparable way to a cannon by affecting models in its path. In this case character models with units can take advantage of the 'Look Out Sir' rule to avoid falling into the chasm.
