Lava emerges from the ground and creates a river of molten rock within range. A river of lava covers the ground in a 60 feet long and 15 feet wide river.
When the river appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 6d10 fire damage, or half as much damage on a successful save.
Each creature that starts its turn within the river takes 6d10 fire damage. A creature takes the same damage when it enters the river for the first time on a turn.
When the spell ends, every creature within the area must make a Strength saving throw or become restrained as the river hardens to dark stone. As an action, a creature can make a Strength check against your spell save DC, escaping on a success.
At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 1d10 for each slot level above 7th.
