This spell makes any vehicle ride smoothly, without regards to most types of rough terrain. Passengers and objects travelling in or on the vehicle suffer no ill effects (motion sickness, being shattered from jarring or vibration, etc). The spell is broken if the vehicle is rocked or turned over by assault, if it tries to travel over terrain impossible for the vehicle to traverse (a wagon trying to float, or a boat being dragged accross land), or if the terrain becomes incredibly rugged (a boat in a gale, or a cart climbing a recent rockslide with many potholes and large rocks). This spell will work on everything from canoes to flying carpets to elevators. It will work on vehicles pulled or powered by animals or people (rowboats, wagons, etc), but will not work where the "vehicle" is mostly or completely a living creature (saddles, howdahs, etc).
Arcane Material Component: A small, smooth, perfectly spherical ball of iron.
