Spell Description
By striking the ground, you create a yawning rift full of sulfuric lava that splits the earth. Create a rift in the round 1,000 ft long by 10 ft wide. The rift consists of twenty 50 ft long by 10 ft wide segments joined from end to end.

Make two separate magic attacks against creatures and structures in the line. The first targets FORT; On a hit, deal 12d6 blunt damage. On a miss, 1⁄2 damage. Structures take double this damage and their DT is ignored. The second targets REF; On a hit, the creature or portion of a structure falls into the rift, which contains molten lava. Creatures and structures that fall into the rift take 40d6 fire damage. Creatures that start their turn in the lava or move through it also take this damage.

Climbing out of the rift requires a STR check against a DC of 10 + your magic attribute, unless a creature has a climb speed.

The rift remains indefinitely and produces noxious fumes and thick smoke. The area within a 1-mile radius of the rift becomes dim light when it would otherwise be bright light. On an hourly basis, there is a 5% chance that noxious gasses emerge from the center of each 50 ft segment. When this occurs, the gasses make an attack using your magic attribute against the FORT of each creature within 50 ft of the rift. On a hit, creatures begin suffocating until they move at least 150 ft away from the rift.
