Move Earth

This spell moves dirt (clay, loam, sand), possibly collapsing embankments, moving hillocks, shifting dunes, and so forth. However, in no event can rock formations be collapsed or moved. The spell can move up to one 150 feet square (up to 10 feet deep) per round. This spell does not violently break the surface of the ground. Instead, it creates wavelike crests and troughs, with the earth reacting with glacier-like fluidity until the desired result is achieved. Trees, structures, rock formations, and such are mostly unaffected except for changes in elevation and relative topography. The spell cannot be used for tunneling and is generally too slow to trap or bury creatures. Its primary use is for digging or filling moats or for adjusting terrain contours before a battle. This spell has no effect on earth creatures.
