Silt Tides (Reversible)

With this spell a priest can create an area of abnormally low tides in the Sea of Silt. The area of silt affected is a circle with a radius of 10 yards per level of the caster. Within the circle, the silt drops 10 feet below its normal level, which is usually enough to expose the maze of rock walkways common to the coastal areas of the Sea. The spell's area of effect moves with the caster, so he can travel the rock walkways while exposed to the air. Strong winds and the like affect the silt normally.

The reverse of this spell, high silt tides, causes the silt to rise 10 feet higher within the circular area of effect. The silt can overwhelm vessels or wading creatures that are not tall enough to wade through ten additional feet of depth.

If cast outside the Sea of Silt, this spell has no effect. The material component is a small, oval lump of lead that has been cast by moonlight.
