Traceless Travel

(Adaptation of 2e Al-Quadim spell) (Province: Sand)

This spell allows the recipient, either an individual or his mount, to tread upon the sandy ground without leaving a visible trace. On other terrains, the spell is worthless.
The caster must gather a handful of sand. Then they must shed a tear that falls to the ground. The teardrop leaves a visible stain, marking the spot where the spell effect begins. From that point on, the sand (or sandy terrain) will not show the recipient's footprints--or any other physical track they normally would make. The sand creates a cushion of air above its surface upon which the recipient walks. The cushion remains for one round, allowing a pursuer or companion who follows closely to be similarly concealed, provided he takes the same route.

You radiate a concealing aura in a 30-foot Emanation for the duration. While in the aura, you and each creature you choose have a +10 bonus to Dexterity (Stealth) checks and leave no tracks. When cast at a higher level, the spell duration increases by 1 Hour/level.

Although it is invisible to the naked eye, the path traveled by the recipient radiates magic for 1d4 hours after casting, so visible to a Detect Magic spell regardless of how much the sand or air is subsequently disturbed. Further, creatures that track by scent or heat are not thwarted by this spell.
As noted, the material components of this spell are a handful of sand and the caster's teardrop.
