Depthsounder

This spell provides the caster with an estimate of the water depth below the caster and within the range of the spell. The estimate is accurate to within 10% of the real value. It is important to note that the spell reports the average local water depth within the area of effect. This means that if the water depth varied from 30’ to 60’ within a very small distance, the spell would report an average depth of 45’.

This spell is most commonly used to navigate through shallow water. The caster takes a position in the prow of the ship, casts the spell, and then gives steering directions.

The material component is a small black stone, which the mage tosses into the water while casting the spell.
