"Earthen fissures, come forth and engulf these pathetic souls!"

You create an intense seismic disturbance at a point on the ground.

For the Duration, an intense tremor rips through the ground, and shakes creatures and structures in contact with the ground in that area.

The ground in the area becomes difficult terrain. Each creature on the ground that is concentrating must make a CON saving throw. On a failed save, the creature's Concentration is broken.

When you cast this spell and at the end of each turn you spend concentrating on it, each creature on the ground in the area must make a DEX saving throw. On a failed save, the creature is knocked

Prone
.

This spell can have additional effects depending on the terrain in the area, as determined by the DM.

Fissures. Fissures open throughout the spell's area at the start of your next turn after you cast the spell. A total of 1d6 such fissures open in locations chosen by the DM. Each is 1d10 x 4m deep, 4m wide, and extends from one edge of the spell's area to the opposite side. A creature standing on a spot where a fissure opens must succeed on a DEX saving throw or fall in. A creature that successfully saves moves with the fissure's edge as it opens. A fissure that opens beneath a structure causes it to automatically collapse (see below).

Structures. The tremor deals 50 BLUNT damage to any structure in contact with the ground in the area when you cast the spell and at the start of each of your turns until the spell ends. If a structure drops to 0 HP, it collapses and potentially damages nearby creatures. A creature within half the distance of a structure's height must make a DEX saving throw. On a failed save, the creature takes 5d6 BLUNT damage, is knocked prone, and is buried in the rubble, requiring a DC 20 STR (Athletics) check as an action to escape. The DM can adjust the DC higher or lower, depending on the Nature of the rubble. On a successful save, the creature takes half as much damage and doesn't fall prone or become buried.
