Control Lava

Until the spell ends, you control any molten lava inside an area you choose that is a cube up to 100 feet on a side. You can choose from any of the following effects when you cast this
spell. As an action on your turn, you can repeat the same effect or choose a different one.

Overflow. You cause the lava in an area to rise by as much as 10 feet. If the area is underneath cooler rock, the lava slowly breaks through the surface to rise. Immediately upon entering the lava and every time it begins its turn in the lava, a creature must make a Constitution saving throw, taking 3d8 fire damage on a failure and half as much on a success.
The lava remains at this elevated level until the spell ends or you choose a different effect.

Part Lava. You cause lava in the area to move apart and create a trench. The trench extends across the spell’s area, and the separated lava forms a wall to either side. The trench remains until the spell ends or you choose a different effect.

Redirect Lava Flow. You cause flowing lava in the area to move in a direction you choose, even if the lava has to flow over obstacles, up walls, or in other unlikely directions. The lava in the area moves as you direct it, but once it moves beyond the spell’s area, it resumes its flow based on the terrain conditions. Flammable objects in the lava flow’s path that aren’t being worn or carried are ignited. When a creature enters the lava or starts its turn there, it must make a Constitution saving throw, taking 3d8 fire damage on a failure and half as much on a success.

The lava continues to move in the direction you chose until the spell ends or you choose a different effect.
