the only mermaid spell that works

after 1 minute of chanting, a creature you are touching legs turn into a fish tail painlessly and the creature gain the ability to breath water and air. for the next hour the creature's swimming speed is 40 feet and it can breath water but their walking speed drops to 5 feet.

you can cast this spell on your self. but please do so while in a body of water unless a friend is their to carry you as you'll have no legs but a fish tail.
