Range:  10 yards
Components:  V, S, M
Duration:  1 round per level
Casting Time:  1
Area of Effect:  One person
Saving Throw:  Negates

This spell forces the recipient to sink to the bottom of a body of water at the rate of 20 yards per round unless they make a saving throw versus spell. No amount of swimming or struggling will stop the victims descent. However, a rope or other secured object that can hold the weight of the victim will stop the sinking.
The spell recipient will sink for a number of rounds equal to the caster's spell level. If they touchdown at the bottom of the water before the spell duration expires, they will simply be unable to leave the ground until the spell wears off. When this spell is cast in the elemental plane of water, the victim will sink in whatever direction their feet were facing at the time of casting. This spell will also affect those that are swimming on the surface of a body of water.
The reverse of this spell, surface, will force the recipient to float to the surface of the water for the duration of the spell.
The material component of this spell is a small ball of lead.
