Transmutation

Summary
Transmutation is the ability to alter the form of energy, beings, objects, matter, etc. to change it into something else. This ability has a variety of applications, including transmuting nearby objects into useful items or nullifying attacks by turning them into something else. More specialized versions can turn forcibly transmute or transform targets into other inanimate objects or vastly weaker beings (i.e. a common toad), effectively incapacitating or killing them.
