Spell: Aqueous Harmony
The elementalist and up to a dozen allies are charmed with powers of water-breathing, a tolerance for the pressure and cold of the deeps, and the ability to see through water as if it were well-lit air. Ensorceled beings may move freely while in the water at their usual movement rate and their attacks and projectile weapons are not hindered by the medium, nor are their possessions soaked or damaged. The spell lasts for one hour per caster level, but will not naturally end so long as a subject is still at least partially submerged. Only the caster or magical dispelling can stop it under those circumstances.
