Threatening Underwater

You unleash a stream of panic at a swimming creature you can see within range. If the target can hear you (though it need not understand you), it must succeed on a Wisdom saving throw or become afraid of the water.  They must spend their movement on their next turn trying to escape from the water.  If they are underwater, they try to swim to the surface.  If they are at the surface, they try to swim towards dry land.
