You create a seismic disturbance at a point on the ground and an intense tremor arises, causing rocks to hurl from the area.

When you first cast this spell, rocks are formed and hurled from the ground, and the sudden seismic disturbance forces all creatures to make a Dexterity saving throw, taking 7d4 Earth damage and potentially being knocked

Prone

Critical Success (+10). The target is unaffected.
Success. The target takes half damage.
Failure. The target takes full damage and is knocked Prone.
Critical Failure (–10). As failure, except the target takes 1.5× damage.

A creature must make the same Dexterity saving throw when it first enters the area on a turn, and whenever it ends its turn in the area.

The area affected by this spell becomes Difficult Terrain from all the rubble and rocks that are being formed.

Structures take double damage from this spell.

At Higher Levels: The damage increases by 2d4 for each spell level increase.
