Shattered Earth

You scatter loose stones in a 25-foot cone and turn the ground into rough terrain. While the spell lasts, the terrain in the area becomes difficult terrain. Each creature within the area that Dashes, is forcibly moved, or uses an action, bonus action, or reaction to move must make a Dexterity saving throw. On a failure, the stones beneath the creature shatter and the creature takes 3d8 incisive damage for each 5-foot square it crosses. Each creature that is moved involuntarily makes the saving throw with disadvantage. After the stones shatter, the ground along the creature’s path is no longer affected by the spell.

At the end of the duration, all remaining stones shatter. Each creature within the remaining area must make a Dexterity saving throw. On a failure, the creature takes 3d8 incisive damage.

The spell ends early when you use your action or bonus action to dispel it. Ending the spell this way prevents the remaining stones from shattering.

At Higher Levels. When you cast this spell by spending Mana points equal to a 6th-level spell or higher, the damage increases by 1d8 for each spell level above 5th.
