Still Waves
This spell immobilizes normal wave motion in a 20-foot by 20-foot area. It stills the waters, permitting drowning sailors, lost cargo, or other items to be fished out of heavy seas. When cast during a heavy chop, the ocean within the area of effect becomes as still as pond water; if seas are heavier than this (as during a violent storm), the wave action is reduced to a heavy chop. If the sea is agitated by an elemental or hostile magic, still waves fails unless the spellcaster makes a saving throw vs. spell. If the seas are already affected by still waves, a hostile spellcaster or elemental must make a successful saving throw vs. spell to disrupt the magically calmed waves.
