This spell creates a magical link between a body of water within range and another body of water, at any location within 500 miles, on the same plane of existence. You must have seen or touched the destination body of water at least once before. For the duration, any creature can step into the target body of water and exit from the destination body of water by using 5 feet of movement.   Both bodies of water must be large enough for the creature attempting to pass through to become fully submerged. If either body of water isn’t large enough for the creature to become fully submerged, there’s a 25 percent chance that the creature exits from a random body of water on the same plane of existence.
