Rock to Mud

Spell, Elemental Magic, level 5

Turns a large mass of rock into soft mud that slows creatures and wagons to a crawl; it can also be reversed.

From the book

The caster transforms as much as 100x100x100 ft. of rock into soft, oozing mud. Creatures and wagons in it can move at only a quarter of their normal rate. The change is permanent unless dispelled, and the spell can also be cast in reverse. There is no save.

A scene

The Suti came down the stony slope at the caravan in a howling line of camels, and the druid Suhail did not reach for a weapon. He spread his hands toward the hillside. Rock sagged, softened and ran, and the whole slope beneath the raiders turned to a brown, oozing mire. Camels floundered chest-deep, bellowing, crawling forward at a quarter of their pace while the caravan guards picked their shots. The Suti who survived never came that way again. Neither did anyone else: the pass in the Wilderness of Zin is a bog to this day.
