Move earth

Move earth is a transmutation spell that digs trenches and builds hills.

Effects
Move earth moves dirt (clay, loam, sand), possibly collapsing embankments, moving hillocks, shifting dunes, etc. However, in no event can rock formations be collapsed or moved. The area to be affected determines the casting time. For every 150-foot square (up to 10 feet deep), casting takes 10 minutes. The maximum area, 750 feet by 750 feet, takes 4 hours and 10 minutes to move.

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.

Material components
The spell required verbal, somatic and material components. The materials required were a mixture of soils (clay, loam, and sand) in a small bag, and an iron blade.

History
The spell was attributed to Netherese arcanist Proctiv in -2095 DR and was originally called Proctiv's earthmove.
