Trench

By making a scooping gesture, you cause the ground to slowly sink in an area 5 feet wide and 60 feet long, originating from a point within range. When the casting is finished, a 5-foot-deep trench is the result.

The spell works only on flat, open ground (not on stone or paved surfaces) that is not occupied by creatures or objects.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can increase the width of the trench by 5 feet or the length by 30 feet for each slot level above 2nd. You can make a different choice (width or length) for each slot level above 2nd.
