Capabilities
User with this ability either is or can transform into a merfolk (male or female), with the upper body of a humanoid and the lower body (in taur-style) of either that of a fish or cetacean. Some are able to transform completely into humanoid form to move on land and some can split their tail into legs. Others have to find other ways to move while on land.

Merfolk are sometimes depicted as perilous creatures associated with floods, storms, shipwrecks, and drowning. In other folk traditions (or sometimes within the same tradition), they can be benevolent, bestowing boons, teaching or even falling in love with humans.
