The caster causes the ground to split open creating a fissure in the ground. The length and depth of the fissure depends on the amount of MC used with a single 1 cubic feet long and deep fissure being created for every 1 MC used. Those in the path of the fissure must attempt a Dexterity Save against the Spell DC or else they fall into the fissure being knocked prone and taking any additional fall damage depending on the fissure’s depth.
