Choose an area of terrain no larger than 40' on a side within range. You can reshape dirt, sand, or clay in the area in any manner you choose for the duration. The extent of any such changes can't exceed half the area's largest dimension. It takes 10 min for these changes to complete. Because the terrain's transformation occurs slowly, creatures in the area can't be trapped or injured by the ground's movement. At the end of every 10 min, you can choose a new area of terrain to affect within range.

This spell can't manipulate natural stone or stone construction. Rocks and structures shift to accommodate the new terrain. If the way you shape the terrain would make a structure unstable, it might collapse. Similarly, this spell doesn't directly affect plant growth. The moved earth carries any plants along with it.
